Ultrasound Guidance in Paravertebral Injections of Oxygen-Ozone: Treatment of Low Back Pain

Background: Paravertebral injection of ozone is an established clinical practice for the treatment of Low Back Pain (LBP). The role of Ultrasound Guidance (USG) in mini invasive procedures has become important in many clinical practice thanks to the greater precision this technique can add. As matter of fact, a large volume of ozone in a single administration may have some adverse or side effects. In this study we wanted to verify if the use of USG in Oxygen/ Ozone (O2/O3) infiltrations could allow the administration of a smaller volume of gas mixture, increasing the safety and the comfort of the procedure itself, obtaining however similar or better results in pain decrease. Methods: We compared two groups of 25 patients affected by LBP, undergoing 10 infiltrations of O2/O3, by using USG (group U) or only anatomical landmarks (group AL). Pain intensity, by calculating Visual Analogical Scale (VAS) difference before and after the treatment, and the discomfort were evaluated in both groups. Results: The mean of the VAS before the treatment was 6.44 in group U and 6.48 in group AL. The mean of the VAS after the treatment was 2.22 in group U and 3.04 in group AL. The mean of discomfort rate was 2.84 in group U and 5.44 in group AL. The number of patients with unbearable discomfort was 0 in group U and 7 in group AL. Conclusions: As many other treatment, also paravertebral injections of O2/O3 benefits of the advantages of the US device which makes this treatment safer and more accurate

Stool Testing for Colorectal Cancer Screening

Colorectal cancer (CRC) screening has been shown to reduce CRC incidence and mortality and is widely recommended. However, despite the demonstrated benefits of screening and ongoing efforts to improve screening rates, a large percentage of the population remains unscreened. Noninvasive stool based tests offer great opportunity to enhance screening uptake. The evidence supporting the use of both fecal immunochemical testing (FIT) and stool DNA (sDNA) has been growing rapidly and both tests are now commercially available for use. Other stool biomarkers (eg, RNA and protein based) are also actively under study both for use independently and as adjuncts to the currently available tests. This mini review provides current, state of the art knowledge about noninvasive stool based screening. It includes a more detailed examination of those tests currently in use (ie, FIT and sDNA) but also provides an overview of stool testing options under development (ie, protein and RNA)

Sustainability Determinants of Cultural and Creative Industries in Peripheral Areas.

Cultural and Creative Industries (CCIs) are increasingly recognized as part of the global economy and of growing importance for sustainable local development. However, the exploitation of their full potential depends on several issues concerning their entrepreneurial dimension and the context where they operate. The paper deals with these issues having the scope to investigate the main determinants of CCIs’ sustainability in peripheral areas, to understand what kind of policy could better support the survival of CCIs and development in these areas, according to an end-user perspective. The research is part of an Interreg Greece-Italy project carried out from mid-2018 until the end of 2020 with specific reference to CCIs in Apulia (IT) andWestern Greece (EL). A two-step mixed methodology has been used to figure out regional specializations and the specific aspects of the entrepreneurial structure and business sustainability in the cultural and creative sector (CCs). In the end, the paper shows and discusses the main determinants considered crucial for CCI sustainability, suggesting guidelines for local authorities supporting their economic development

Associations of chronic diarrhoea with non-alcoholic fatty liver disease and obesity-related disorders among US adults

Mechanisms explaining observed associations between diarrhoea and obesity or increased body mass index (BMI) are unclear. Objective: To assess associations of bowel patterns with BMI, metabolic syndrome (MS), non-alcoholic fatty liver disease (NAFLD) and other obesity-related disorders. Design: We performed a cross-sectional analysis of data from adults who completed bowel health questions for the 2005 to 2010 cycles of the National Health and Nutrition Examination Surveys. Relationships were examined using multinomial logistic regression. Confounding effects of demographics, smoking, alcohol and BMI were examined by sequential modelling. Results: Among 13 413 adults, weighted prevalence rates of constipation and diarrhoea were 8.9% and 6.6%, respectively. Mean BMI was associated with bowel patterns (p<0.001), and was higher with diarrhoea (30.3 kg/m2) versus normal bowel patterns (28.6 kg/m2) and with diarrhoea versus constipation (27.8 kg/m2). NAFLD was more prevalent (ORs, 95% CI) in diarrhoea versus normal bowel patterns (OR=1.34, 95% CI 1.01 to 1.78) or constipation (OR=1.45, 95% CI 1.03, 2.03) in adjusted analyses. The higher prevalence of MS in diarrhoea versus constipation (OR=1.27, 95% CI 0.97 to 1.67) was not independent of BMI. Conclusions: These findings suggest an association between diarrhoea and NAFLD that is independent of BMI

Patient Understanding of Benefits, Risks, and Alternatives to Screening Colonoscopy

While several tests and strategies are recommended for colorectal cancer (CRC) screening, studies suggest that primary care providers often recommend colonoscopy without providing information about its risks or alternatives. These observations raise concerns about the quality of informed consent for screening colonoscopy

Adherence to Surveillance Guidelines in Nondysplastic Barrett’s Esophagus

Introduction: Surveillance patterns in Barrett's esophagus (BE) are not well characterized. Guidelines published between 2002 and 2008 recommended surveillance esophagogastroduodenoscopy (sEGD) at 3-year intervals for nondysplastic BE (NDBE). We assessed guideline adherence in incident NDBE in a Veterans Affairs (VA)-based study. Methods: At a single VA center, we identified incident cases of biopsy-confirmed NDBE between January, 2006 and December, 2008. We excluded patients aged 76 years and above and those who developed BE-associated dysplasia or cancer during follow-up. All sEGDs through October, 2014 were documented. Our primary criteria classified cases as guideline adherent if a sEGD was performed within 6 months of each expected 3-year surveillance interval; in cases with >=2 sEGDs, 1 sEGD >6 months, and <=1 year outside an interval was allowed if the average interval was between 2.5 and 3.5 years. Comorbidity, primary care encounters, presence of long-segment BE (LSBE), endoscopist recommendations, and Charlson comorbidity index (CCI) were assessed. Results: We identified 110 patients (96.4% male, 93.6% white) with mean age 58.9+/-8.5 years at index EGD. Median follow-up was 6.7 years (range, 3.7 to 8.6). Thirty-three (30.0%) cases were guideline adherent; 77 (70.0%) cases were nonadherent, including 52 (47.3%) with irregular surveillance and 25 (22.7%) with no surveillance. Forty cases (14 adherent) had 1 sEGD, 36 (18 adherent) had 2, 8 (1 adherent) had 3, and 1 nonadherent case had 4. Adherent cases were significantly older (61.5 vs. 57.9 y, P=0.04), and tended to have more LSBE (33.3% vs. 20.8%, P=0.16). There were no differences between adherent and nonadherent cases in annual primary care encounters (72.7% vs. 66.2%, P=0.66), CCI>=4 (15.2% vs. 15.6%, P=0.95), biopsy-positive sEGDs (75.8% vs. 76.6%, P=0.92), and any recommendation for subsequent surveillance (81.8% vs. 77.9%, P=0.65). A logistic regression model using age, CCI, and LSBE showed an independent association between adherence and older age (P=0.03). Conclusions: In a single-center VA cohort, sEGD of NDBE was mostly nonadherent to guidelines. Adherent cases were older at baseline with a trend toward more LSBE. A larger study is needed to identify medical and social factors associated with adherence or nonadherence to surveillance

Thinking Big About Small Adenomas: Moving Toward "Precision Surveillance"

Quality metrics and technological advances for colonoscopy are contributing to detection of more diminutive and small adenomas, increasing the proportion of persons undergoing surveillance for non-advanced neoplasia. In this issue, Kim and colleagues report surveillance colonoscopy findings in average-risk Koreans who had one or more adenomas on a first screening colonoscopy and found a similar risk of metachronous advanced neoplasia between those with 1-2 non-advanced adenoma (the "low-risk adenoma" group) and those with 3 or more small adenomas. The validity, generalizability, and clinical implications of the findings are considered along with recent similar studies. In sum, these studies support expanding the low-risk subgroup to include up to four diminutive tubular adenomas and perhaps persons with up to four small tubular adenomas. They also prompt consideration of "precision surveillance" that considers features of not just the polyps, but of the patient and endoscopist

Genetic pathways, prevention, and treatment of sporadic colorectal cancer

Epithelial cancer of the colon and rectum, also known as colorectal cancer (CRC), results from a progressive accumulation of genetic and epigenetic alterations that lead to uncontrolled growth of colonocytes, the cells lining the colon and rectum. CRC is the second leading cause of cancer-related deaths and the third most common cancer in men and in women in the U.S. Of all the patients diagnosed with CRC every year, it is estimated that the vast majority of CRCs are non-hereditary "sporadic cancers" with no apparent evidence of an inherited component. Sporadic CRC results from the cumulative effects of multiple genetic and epigenetic alterations caused by somatic mutations, which may themselves be the indirect result of several environmental factors. This review examines our current understanding of the major genetic alterations leading to colon cancer, options for prevention and early detection of CRC, and the currently available treatment approaches that may target these different genetic alterations
