Does technetium-99m diethylenetriaminepentaacetate clearance predict the clinical course of idiopathic pulmonary fibrosis?

Clearance of inhaled technetium-99m diethylenetriaminepentaacetate (99mTc-DTPA) is a potential indicator of disease activity and progression in idiopathic pulmonary fibrosis (IPF). The objective of the present study was to evaluate the prognostic value of 99mTc-DTPA scans in IPF. A total of 22 patients (18 males), aged 33 to 80 years with IPF were followed for six to 20 months (mean 13 months). At diagnosis, high resolution computed tomography (HRCT) scans showed a honeycomb pattern with bibasilar reticular opacities in all cases. At T0 (diagnosis) and T1 (follow-up), each patient had pulmonary function tests (forced vital capacity, diffusing capacity of the lung for carbon monoxide and partial arterial O2 pressure), extension of fibrosis evaluated by HRCT visual score and 99mTc-DTPA lung clearance. Results at T0 and T1 were compared, taking into account the whole population and patients with relatively fast and slow 99mTc-DTPA wash-out. 99mTc-DTPA clearance did not show any significant correlation with functional tests or HRCT score. These findings indicate that clearance of inhaled 99mTc-DTPA is not of value in following the progress of IPF

Gastroduodenal Lesions Associated with Portal Hypertension: An Extensive Review

The block of the portal flow by obstacles in prehepatic, hepatic or posthepatic site and alterations of the splanchnic blood flow are the pathological conditions that lead to portal hypertension. The portal hypertension can cause also others gastroduodenal lesions, potentially hemorrhagic, in addition to esophageal varices commonly developed and habitual source of bleeding in these patients. The gastroduodenal lesions associated with portal hypertension, usually encountered in the clinical practice, are portal hypertensive gastropaty, gastric antral vascular ectasia, gastric and duodenal ulcer, isolated gastric varices. The pathophysiology and clinical, diagnostic and therapeutic features of these lesions are examined

Psychometric Properties and Correlates of Precarious Manhood Beliefs in 62 Nations

Precarious manhood beliefs portray manhood, relative to womanhood, as a social status that is hard to earn, easy to lose, and proven via public action. Here, we present cross-cultural data on a brief measure of precarious manhood beliefs (the Precarious Manhood Beliefs scale [PMB]) that covaries meaningfully with other cross-culturally validated gender ideologies and with country-level indices of gender equality and human development. Using data from university samples in 62 countries across 13 world regions (N = 33,417), we demonstrate: (1) the psychometric isomorphism of the PMB (i.e., its comparability in meaning and statistical properties across the individual and country levels); (2) the PMB’s distinctness from, and associations with, ambivalent sexism and ambivalence toward men; and (3) associations of the PMB with nation-level gender equality and human development. Findings are discussed in terms of their statistical and theoretical implications for understanding widely-held beliefs about the precariousness of the male gender role

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Relationship between residual gastric area and weight loss after sleeve gastrectomy: A Cohort study

Background: The aim of this study is to evaluate the impact of the actual size and area of the remnant stomach, as measured by Upper gastrointestinal tract radiography, on weight loss after sleeve gastrectomy.Materials and methods: From May 2017 to December 2019, 56 patients with morbid obesity were admitted to the Department of Medical and Surgical Sciences, University of Foggia and underwent lapamscopic sleeve gastrectomy.Results: 56 patients underwent sleeve gastrectomy with a mean age of 43,5 +/- 11 years of which 40 were female. The mean Excess Weight Loss (EWL) at 1 month was 24,09 +/- 15,04%, at 6 months was 27,07 +/- 19,55% and at 12 months was 69,9 +/- 23,7%. The mean Excess Body Mass Index Loss (EBMIL) at 1 month was 23,1 +/- 12,5%, at 6 months was 56,6 +/- 19,7% and at 12 months was 69,7 +/- 23,7%.The EWL % was correlated with the residual stomach area (RSA) at 1 month (r = -0,242 p = 0,072), at 6 months (r = -0,249 p = 0,064) and at 12 months (r = -0,451 p = 0,0005).The EBMIL % was correlated with the RSA at 1 month (r = -0,270; p = 0,043), at 6 months (r = -0,270; p = 0,043) andat 12 months (r = -0,46; p = 0,0004).Conclusion: A greater postoperative EWL % was correlated with a smaller RSA and this resulted in a statistically significant change at 12 months after surgery

Emergency Surgery for Colon Diseases in Elderly Patients—Analysis of Complications, and Postoperative Course

Background and Objectives: Colon diseases can turn in a clinical emergency with the onset of some important complications. Some critical conditions are more common in aged patients because they are frailer. The aim of this study is to examine patients over 80 years of age who are undergoing emergency colorectal surgery, and evaluating the aspects associated with post-operative complications and other problems in the short term. Methods: From November 2020 to February 2022, we included 32 consecutive patients older than 80 undergoing emergency surgery due to colon diseases. We collected and analysed all demographic and operative data, and then applied CR-POSSUM score and correlated this with postoperative hospital stay and the onset of postoperative complications according to the Clavien Dindo classification. Results: Postoperative factors were selectively evaluated based on the clinical scenario and different colic pathologies. There were no statistically significant differences, in terms of postoperative hospital stay, postoperative complications, reoperation rate and 30-day mortality. The number of cases of blood transfusions was significant and was more numerous in cases of intestinal perforation and bleeding cases. The value of the Operative Severity Score in bowel perforations was significantly higher. Conclusions: The use of a score to stratify the risk is a useful tool, especially in elderly patients undergoing emergency surgery. The CR-POSSUM score was important for predicting morbidity in our study. Emergency manifestations of colon diseases in the elderly show higher morbidity and mortality rates. The effect of age on outcome is a concept that needs to be emphasized, so further investigation is needed

Leak after sleeve gastrectomy with positive intraoperative indocyanine green test: Avoidable scenario?

Background: The staple line gastric leak (GL) is estimated to be the most serious complication of the sleeve gastrectomy. The use of indocyanine green (ICG) has been introduced in minimally invasive surgery to show the vascularization of the stomach in real time and its application to the gastroesophageal junction (GE) during Laparoscopic Sleeve Gastrectomy (LSG) seems very promising. Case presentation: We present the case of a 40-year-old female underwent laparoscopic sleeve gastrectomy. Intraoperative indocyanine green test showed a small dark area in the proximal third of the staple line reinforced with fibrin glue. Two weeks later the patient presented to the emergency room (ED) with abdominal pain, fever, vomiting, intolerance to oral intake and the evidence of a leak on the abdomen Computer Tomography (CT). The UIN for ClinicalTrial.gov Protocol Registration and Results System is: NCT05337644 for the Organization UFoggia. Conclusions: This case report shows that intraoperative ICG test can be helpful in determining which patients are at greater risk of the leak and, more importantly, the cause of the leak but further tests are needed to determine if the ICG predicts leak due to ischemia

Anastomotic leak test using indocyanine green during laparoscopic Roux-en-Y gastric bypass: A cohort study

Background: Indocyanine green (ICG) can be injected into the human bloodstream and it allows us to show stomach vascularity in real time. The aim of our study is to observe the preliminary results of the application of indocyanine green fluorescence (IGF) during laparoscopic Roux-en-Y Gastric Bypass (RYGB in our center and how the perfusion of the gastro-jejunal anastomosis affects the onset of fistula. Materials and methods: 30 consecutive patients underwent RYGB with ICG fluorescence angiography at our center from January 2020 to December 2021.5 ml of ICG were then injected intravenously to identify the blood supply of the stomach and the gastro-jejunal anastomosis. The UIN for ClinicalTrial.gov Protocol Registration and Results System is: NCT05476159 for the Organization UFoggia. Results: In the RYGB tested with ICG, we all have adequate perfusion but despite this a methylene blue test was positive and allowed us to reinforce the suture of the gastro-jejunal anastomosis. Conclusion: Intraoperative ICG testing during laparoscopic RYGB may be helpful in determining which patients are at an increased risk for leakage but multiple factors concur to the pathophysiology and the incidence of gastric fistula not only the perfusion

Bariatric surgery: to bleed or not to bleed? This is the question

Background Bariatric surgery procedures are the most successful and durable treatment for morbid obesity. Hemorrhage represents a life-threatening complication, occurring in 1.3-1.7% of bariatric surgeries. Materials and methods We examined patients undergoing Bariatric Surgery from July 2017 to June 2020 (Group A) and those operated from July 2020 to June 2022 (Group B) in our Department. Starting from July 2020 we have implemented intraoperative measures to prevent postoperative bleeding, increasing mean arterial pressure (MAP) by 30% compared to preoperative and reducing the pneumoperitoneal pressure of CO2 to 8 mmHg in the last 15 min of the operation. Results The study gathered 200 patients divided into the two described groups. The mean age of Group A is 44 +/- 8.49 and 43.73 +/- 9.28. The mean preoperative BMI is 45.6 kg/m(2) +/- 6.71 for Group A and 48.9 +/- 7.15 kg/m(2) for Group B. Group A recorded a mean MAP of 83.06 +/- 18.58 mmHg and group B a value of 111.88 +/- 12.46 mmHg (p value < 0.05 and z-score is 4.15226 and the value of U is 13,900). We observed 9 cases of bleeding in group A, most of them being treated with medical therapy and transfusions; only 1 hemodynamically unstable patient underwent re-laparoscopy. We reported only 2 cases of bleeding in group B, one of which required blood transfusions. Conclusion From our study we can conclude that increasing mean arterial pressure (MAP) by 30% compared to preoperative and reducing the pneumoperitoneum pressure of CO2 to 8 mmHg in the last 15 min of the operation led to a decrease in bleeding cases in group B and, most importantly, all the bleedings were easily controllable with medical therapy and/or transfusions. These measures allowed us to reduce postoperative bleeding
