Percutaneous Balloon Compression for the Treatment of Trigeminal Neuralgia: A Review of 10 Years of Clinical Experience.

Trigeminal neuralgia (TN) is defined as a spontaneous painful sensation in the trigeminal nerve territory. The pain intensity of TN is classified into different grades of suffering that affect a patient's quality of life. Percutaneous balloon compression of the ganglion is a neurosurgical option that is easy, reproducible, and can reduce the morbidity of TN. We retrospectively analyzed all patients treated with trigeminal nerve percutaneous balloon compression at the Clinical Hospital of the University of Chile between January 2012 and May 2022.Data collected from electronic records included demographic information, medical and surgical history, type of anesthesia and drugs used during surgery, balloon inflation time, surgery time, operative room time, intraoperative events, postoperative complications, duration of hospitalization, and duration of follow-up. Results: We identified 63 patients who met our inclusion criteria. The median patient age was 62 years (interquartile range [IQR] 57-69 years). Sixty-five percent of the patients were female. The simultaneous involvement of the second and third branches of the trigeminal nerve was the most frequent symptom. Before surgery, the patients experienced an average of 6.6 years of pain (IQR 2-10 years). Right neuralgia was the most frequent laterality type (69%). Forty percent of the patients had a previous surgical procedure for neuralgia, with treatment failure being the most frequent surgical indication (63%). According to the procedure, the mean balloon insufflation volume was 0.89±0.12 mL with a median compression time of 2.5 min (IQR 2.1-4.0 min). No hemorrhagic complications were observed. Furthermore, during follow-up, there were no surgical complications among any of the patients; however, 6.4% of patients required a second intervention. The pain-free period was two years in 60% of patients and five years in 23% of patients. TN is a painful condition. Although there are multiple surgical approaches, we believe that percutaneous balloon compression is an excellent alternative treatment option that offers high effectiveness, low morbidity, and low hospital stay.

Perceptions of Increases in Cost of Living and Psychological Distress Among Older Adults.

Objectives: This article examines whether older adults' perceptions of an increase in their cost of living during a time of rapid inflation are associated with multiple aspects of psychological distress, as well as whether mastery buffers these associations. Methods: Data were derived from a two-wave longitudinal survey of older adults gathered in 2021 and 2022 (N = 4,010). Multiple regression models examined symptoms of depression, anxiety, and anger. Results: Perceptions of moderate or large increases in cost of living were associated with higher levels of distress at follow-up. Taking baseline financial strain, mastery, and psychological distress into account weakened these associations, but perceptions of a large increase in cost of living were still substantially linked with anger and anxiety. Mastery also buffered associations with anxiety and anger. Discussion: Macroeconomically derived adversities can shape anxiety and anger in later-life, but these mental health consequences fall more heavily on individuals possessing lower levels of mastery.

Retailing in times of soaring inflation: What we know, what we don't know, and a research agenda

Inflation is back – with a vengeance. Following the highly disruptive years of the pandemic, the world has experienced inflation levels not seen for many decades. A “perfect storm” of underlying causes including expansionary monetary and fiscal policies during the pandemic, pent‑up demand, supply-demand imbalances and commodity-driven cost pressures due to unfavorable weather conditions in various regions and Russia's invasion of Ukraine, all conspired to steeply increase consumer price levels around the world. While current inflation levels are not unprecedented (they were even higher in the 1970s and 1980s), the decades-long period of extremely low inflation experienced in most countries means that current inflation rates continue to shock consumers, manufacturers and retailers. Equally, academic research has very little to say about how to conduct marketing in inflationary times, and that is why this paper presents an overview of what we know, what we don't know and what we argue we should know in the form of a research agenda.We first review key takeaways from prior inflation-focused research in the marketing literature, along with insights that could be derived from related studies that considered other causes of disposable-income reductions. However, given that the inflation literature is sparse, while insights from other forms of disposable-income reduction may not automatically generalize to the current inflationary setting, we identify various knowledge gaps along with a wide-ranging set of questions in need of further research in marketing and retailing. We do so, in the spirit of the Empirics-First approach to relevant knowledge generation, by identifying several frequently used retailer-initiated coping strategies. We subsequently circle back to pertinent prior literature to help with the interpretation of the observed patterns, identify best practices, and warn against potential pitfalls. We hope that this article will inspire cutting-edge research into the consumer-, retailer- and marketing consequences of extreme inflation, a worldwide problem that affects us all and is directly linked to the core role of retailing in the supply-chain channel.

Measuring the Contribution of Strategic Commodities to Persistent Inflation; An Effort to Stabilize the Economy

This study aims to analyze the inflation persistence level of the spending group in Blitar Regency and the contribution of 11 commodities or goods/services groups to the formation of inflation persistence in Blitar Regency. In addition, this study also looks at the role of the Regional Inflation Control Team (TPID) in controlling inflation in the regions. This study uses monthly inflation time series data and CPI for 11 commodity groups in Blitar Regency from 2020 to 2020 to 2020 s.d. 2022 obtained from the Blitar Regency Central Bureau of Statistics and publications from Bank Indonesia, the estimation method in this study uses the Univariate Autoregressive Model (AR) and Partial Adjustment Model (PAM) approaches. The results of the study prove that inflation in Blitar Regency has a high level of persistence which is reflected in the time it takes for inflation to return to its equilibrium level, which is 19 months. The persistence of inflation in Blitar Regency was influenced by shocks that occurred in the housing, water, electricity, gas, and fuel group as well as the transportation group as a representative of the administered prices component and the food, beverage, and tobacco group as a volatile food component. group. This research implies that this research can be used as a reference in determining the right time in determining policies by the government, especially in the regulated price group. In addition to controlling inflation in volatile food components due to shocks such as bad weather, TPID can collaborate with relevant agencies to use technology to minimize the impact of climate change and maximize the potential of regional superior products/commodities, and maximize production to maintain supply availability.

Income Diversification, Bank Volatility Risk and Performance in Low- and Middle-income African Countries: Evidence from Normal and Crisis Periods

Using panel data from 2000 to 2019 for low-income and middle-income African countries, this study examined what determines income diversification and its impact on bank risk and performance. Based on the system’s generalized method of moments and least square dummy variable results, high volatility risk, profitability, cost efficiency and high GDP encourage banks to diversify their income. While having lower leverage, a high net interest margin, and during inflationary times, banks are less encouraged to pursue income diversification. Moreover, income-diverse approaches improve profitability in regular and crisis periods for low-income and middle-income countries. However, income diversification does not lower volatility risks during crisis times. The study shows that increasing the cost efficiencies, higher liquidity and leverage ratios positively affects profitability and reduces volatility risk during the non-crisis period. The net interest margin positively influences risk during and after a crisis. The results show that GDP positively connects to a bank’s profitability. The link between profitability and inflation varies based on the analysis’s emphasis (i.e., before, during or after the crisis) and income level (i.e., low income or middle income). This study’s results have significant implications for bankers, regulators and the banking literature on the determinant, merits and risks of income diversification.

Regulating Public Sector Wages in Times of Inflation and Constitutional Restraints

Purpose: The article discusses the impact of public sector wages and inflation on various aspects of a country’s socioeconomic development. Methodology: Using Slovenia as a case study, the article focuses on how inflation impacts collective bargaining and wage regulation in the public sector, as well as the role of constitutional fiscal restraints in collective bargaining in the public sector. The research employs qualitative methods and focuses on patterns in existing documents and empirical case studies, and a comparative method involving Hungary. Findings and Academic contribution to the field: The article examines the impact of inflation on collective bargaining and wage regulation in the public sector. It concludes that inflation, even with (some) constitutional fiscal restraints in place, can affect collective bargaining and wage regulation in the public sector, depending on the bargaining power of unions and employers and specific provisions outlined in collective bargaining agreements and wage regulations.

Nitrate and Conductivity Effects in Fish Embryo-Larvae.

Nitrate concentrations have been rising in surface waters over the last century and now frequently exceed drinking water standards and environmental safety benchmarks globally. Health-wise, these trends are concerning because nitrate has been shown to disrupt endocrine function and developmental outcomes. This project investigated potential sublethal effects of nitrate on developing fathead minnows. Fish were exposed from fertilization through 21 days post fertilization (dpf) to environmentally relevant concentrations of nitrate (0, 2, 5, 10, 25, or 100 mg/L NO3 -N as NaNO3 ). Nitrate effects on hatch timing, heart rate and rhythm at 3 dpf, growth through 21 dpf, swim bladder inflation timing and size, scoliosis, pericardial edema, and mortality were assessed. Because adding NaNO3 increases water conductivity, two conductivity controls were included to match the ionic strength of the 10 and 100 mg/L NO3 -N treatments. Increasing nitrate delayed posterior swim bladder (PSB) inflation in a dose-dependent manner, with possible inhibition of anterior swim bladder (ASB) inflation at higher doses, although nitrate did not affect swim bladder size. Conversely, nitrate did not affect hatch timing or cardiac endpoints at 3 dpf or induce pericardial edema or scoliosis, although there was a noted brood effect on these latter defects. As was observed with increasing nitrate, higher ion concentrations in the conductivity controls caused dose-dependent increases in fish body size at 21 dpf. Increased ionic strength also hastened ASB inflation independent of nitrate. As in other published studies, the observed delay in PSB inflation suggests that nitrate disrupts the thyroid axis and warrants further investigation. Additionally, this work supports the need for conductivity controls in nitrate toxicity studies to distinguish nitrate-specific effects. This article is protected by copyright. All rights reserved.

Comparative evaluation of high versus low pressure pneumoperitoneum in causing acute kidney injury during laparoscopic cholecystectomy

Objective: Aim of our study is to monitor low- and high-pressure pneumoperitoneum effects and find optimum intra-abdominal pressure that is safe to avoid or minimise acute kidney injury. Material & Methods: This study was conducted at Fatima Memorial hospital from May 2022 to November 2022. A total of 80 patients were segregated into two groups of 40 each. Group A had laparoscopic cholecystectomy with 15 mmHg pneumoperitoneum pressure while Group B had 20 mmHg pneumoperitoneum pressure. Patients were monitored postoperatively for creatinine and urine output changes at 8 hours, 24 hours and 72 hours interval. Results: Post operative creatinine rise and fall in urine output was statistically significant between both group indicating 15 mmHg pneumoperitoneum is safer for laparoscopic cholecystectomy to avoid AKI. Operation time, inflation time and blood loss were statistically significant and remain the key factors in predicting AKI after laparoscopic cholecystectomy. Conclusion: AKI is a common but transient condition that can arise after laparoscopic cholecystectomy. It can be minimized by keeping intra-abdominal pressure ≤15mmHg. Operation time, inflation time and perioperative blood loss can predict AKI perioperatively.

Efficacy and Safety of Percutaneous Venoarterial Extracorporeal Membrane Oxygenation Decannulation Using Endovascular Balloon Dilation and Perclose ProGlide Closure Device: Results from the Multicenter SKYLINE Study

The venoarterial extracorporeal membrane oxygenation (VA-ECMO) cannula can be surgically removed, but postoperative complications and surgical staffing issues can be problematic. We previously reported a method of percutaneously removing the arterial cannula of VA-ECMO by combining intravascular balloon dilation and the Perclose ProGlide™ (PP) closure device. In this study, we investigated the efficacy and safety of this percutaneous decannulation of the VA-ECMO. This multicenter, retrospective study involved consecutive patients who underwent percutaneous VA-ECMO decannulation at two cardiovascular centers from September 2019 to December 2021. We analyzed 37 patients in whom the VA-ECMO cannula was removed by the percutaneous procedure with balloon dilation and the PP. The primary endpoint was procedural success of hemostasis. The secondary endpoints were the procedural time, procedure-related complications, and rate of surgical conversion. The patients' mean age was 65.4 years. The approach site of the endovascular therapy (EVT) procedures were the transradial approach (56.8%), transfemoral approach (27.8%), and transbrachial approach (18.9%). The mean balloon diameter was 7.3 ± 0.68 mm, and the mean balloon inflation time was 14.8 ± 7.3 min. The mean procedure time was 58.5 ± 27.0 min. The procedure success rate was 94.6%, procedure-related complication rate was 10.8%, procedure-related death and postprocedural infection rate was 0.0%, surgical conversion rate was 0.0%, and EVT access site complication rate was 2.7%. We concluded that percutaneous VA-ECMO decannulation using a combination of intravascular balloon dilation in EVT and the PP appears to be a safe, minimally invasive, and effective procedure.

Use of Intermittent Aortic Balloon Occlusion: Report from the ABO Trauma Registry

Background: Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is a helpful adjunct in the management of hemorrhagic shock due to bleeding in the abdomen or pelvis. Ischemia distal to the occlusion is a concern; intermittent aortic balloon inflation (i-REBOA) is a novel way to achieve decreased ischemia time.
 Methods: This study was conducted using data from the multinational ABO Trauma Registry. All patients entered between January 2016 and December 2019 were included.
 Results: The sample consisted of 157 patients. There were 57 patients in the i-REBOA group (36%) and 100 in the REBOA group (64%). The groups were similar in gender (P = 0.50), age (P = 0.17), mechanism of injury (P = 0.42), and injury severity score (P = 0.13). The levels of international normalized ratio (INR) (P < 0.01), activated partial thromboplastin time (aPTT) (P < 0.01) and lactate (P = 0.02) were higher in the i-REBOA group. Total balloon inflation times were longer in the i-REBOA group (P < 0.01). Major complication rates did not differ between groups. Mortality rates between groups were similar in the Emergency Department (ED) (3.8% for i-REBOA vs 10.1%; P = 0.17), within 24 hours (43.4% for i-REBOA vs 38.2%; P = 0.54), and at 30 days (63.6% for i-REBOA vs 48.4%; P = 0.07).
 Conclusions: The data from this registry show that i-REBOA is currently being used and may allow for longer total balloon inflation times without higher morbidity or mortality rates.

The effect of elbow position at the time of tourniquet inflation on clinical outcomes.

The aim of this study was to prospectively investigate the effects of elbow position on perioperative and postoperative clinical outcomes during tourniquet inflation. The patients were divided into two groups based on their elbow position during tourniquet inflation: patients with elbows extended group E (30 patients), patients with flexed elbows group F (30 patients). Both groups were compared in terms of perioperative bloodless surgical field, tourniquet pain, time to onset of pain, and pain in the tourniquet area on the first postoperative day, plus elbow-forearm range of motion deficit on both the perioperative and postoperative first day. The bloodless surgical field provided by the tourniquet was 0.46 (0-5) in Group E and 0.4 (0-4) in Group F. Perioperative tourniquet pain started in an average of 51 (33-71) minutes in 4 patients in Group E and 49 (31-74) minutes in 5 patients in Group F. Pain was present in 2 patients in both groups in the postoperative tourniquet area. When the preoperatively measured elbow flexion-extension and forearm supination-pronation deficits were compared with the perioperative values, the deficits were 1%, 2%, 1%, 1% in Group E, and 1%, 1%, 2%, 1% in Group F, respectively. When compared with the postoperative values, 1%, 3%, 1%, 1% in Group E and 1%, 2%, 1%, and 1% in Group F were observed, respectively. There was no statistically significant difference between the two groups, but since repositioning the elbow after the tourniquet is inflated will cause an additional shearing effect on the tissues under the cuff, we recommend inflating the tourniquet in that position in which the operation will be performed in upper extremity surgeries.

Textual Analysis to Empirically Assess the Impact of Economic Crises on Stakeholder Orientation

This study uses textual analysis of annual reports to evaluate the presence of stakeholder theory in times of economic crises. Although the literature on stakeholder tendency in times of crises is scarce and predominantly focused on U.S. and Austrian data, it suggests that adopting the principles of a stakeholder model may lead companies to a more successful crises management outcome. Academic contributions to German-listed companies utilizing textual analysis are limited. Hence, we start by proposing a qualitative textual approach to analyze annual reports of German-listed companies in the DAX from the period 2000 to 2020 to extract relevant information on the tendency to apply shareholder- or stakeholder-theory-related aspects in times of economic crises such as the Global Financial Crises and more recently the COVID-19 crises. We examine our gathered word extractions with a well-found methodological approach based on a comprehensive literature review and perform a logit regression to test formulated hypotheses. By analyzing word frequencies in annual reports that refer to either shareholders or stakeholders we aim to assess the importance that the management of listed companies attaches to each management approach in times of crises. Based on existing literature, we formulate the central research question of whether the word frequency of shareholder-related words in years of economic crises increases compared to years without economic crises. In line with Asel, Posch, and Speckbacher (2011), our research reconfirms that there is no tendency or conflict of both shareholder and stakeholder management in times of economic crises. In a nutshell, our empirical results indicate that there is no statistically significant increase in word frequencies of either shareholder- or stakeholder-related words in years of economic crises present. Finally, we conclude by challenging the effectiveness of either the shareholder or stakeholder orientation in economic crises-like situations and encouraging further empirical research contributions on this field, and utilizing the proposed textual analysis for other essential research questions, such as the presence of AI-related aspects amongst German-listed companies or indications about price increases in times of high inflation.

Abstract No. 27 The Effects of Patient and Procedural Variables of the Lutonix AV Global Registry: Results from the Arteriovenous Fistula Cohort

This is a post-hoc analysis of the results of the Lutonix AV Global Registry (outside the United Sates) focusing exclusively on arteriovenous fistulas (AVFs) with inclusion criteria consistent to those of the Lutonix IDE trial from the United States. Device under investigation was the Lutonix drug-coated balloon (DCB). 131 of the 320 subjects met criteria for inclusion in the analysis. 59.5% (78/131) were male. 50.5% were white and 45.7% Asian population. Among the exploratory outcome measures were safety (freedom from adverse events at 30 days), efficacy [target lesion primary patency (TLPP) at 6 months], effect of inflation time and pressure of the vessel preparation balloon. Primary safety endpoint at 30 days was 95.2%. TLPP at 6 months was 86.7% based on Kaplan-Meier survival analysis. Subjects with DCB inflation time between 2-3 minutes had a TLPP of 89.7% subjects while in those with 0–1 minute inflation time, TLPP was 78.6%. In subjects where vessel preparation pressure was >25atm, TLPP was 94.4%, while in those with < 25atm vessel preparation pressure, TLPP was 84.7%. Subjects whose lesion underwent vessel preparation and had inflation time >2 minutes, TLPP was 89.8%. Median time to event was 336 days. This post-hoc subgroup analysis suggests that in patients with arteriovenous stenotic lesions treated with DCB, procedural variables may influence outcomes. Subjects were reintervention-free for nearly a year.

Analytic solutions of scalar field cosmology, mathematical structures for early inflation and late time accelerated expansion

We study the most general cosmological model with real scalar field which is minimally coupled to gravity. Our calculations are based on Friedmann–Lemaitre–Robertson–Walker (FLRW) background metric. Field equations consist of three differential equations. We switch independent variable from time to scale factor by change of variable {dot{a}}/a=H(a). Thus a new set of differential equations are analytically solvable with known methods. We formulate Hubble function, the scalar field, potential and energy density when one of them is given in the most general form. a(t) can be explicitly found as long as methods of integration techniques are available. We investigate the dynamics of the universe at early times as well as at late times in light of these formulas. We find mathematical machinery which turns on and turns off early accelerated expansion. On the other hand late time accelerated expansion is explained by cosmic domain walls. We have compared our results with recent observations of type Ia supernovae by considering the Hubble tension and absolute magnitude tension. Eighty-nine percent of present universe may consist of domain walls while rest is matter.

Effect of Fixed Tracheal Cuff Volume vs Fixed Tracheal Cuff Pressure on Hemodynamic Parameters and Postoperative Airway Complications, A Prospective Randomized Control Trial in a Tertiary Care Hospital

Background: The current study is aimed to compare the effect of fixed cuff volume and fixed cuff pressure technique on hemodynamic parameters and on postoperative complications.&#x0D; Methods: The prospective, randomised, controlled study was conducted in a tertiary care hospital with 100 patients aged between 18 to 60 yrs. The patients who are undergoing for elective surgeries under general anaesthesia were enrolled after obtaining ethical committee approval. Patients were randomized based on computer generated random numbers into two groups, fixed volume (7ml) group (group V, n-50) and fixed cuff pressure group (group P, n-50). The ETT cuff was filled with 7 ml of air in the fixed volume technique, and in the fixed cuff pressure group -cuff pressure was maintained at 20 cmH2O, after intubation. Tracheal tube cuff pressures were measured by AMBU cuff pressure gauge manometer. Hemodynamic parameters SBP, DBP, MAP and PR were noted at the time of cuff inflation, after extubation in the both the groups. Post-operative sore throat, hoarseness and cough was assessed at the time of extubation in the both the groups.&#x0D; Results: Mean age in both the groups was 41 years. Statistical significance (P&lt; 0.0001) was observed in Group P in systolic blood pressure (SBP), diastolic blood pressure (DBP), MAP, HR whereas no significance was seen in group V. The percentage of post-operative complications like hoarseness, cough, sore throat, and dysphagia were seen to be less in group P when compared to group V.&#x0D; Conclusion: With present data we could conclude that the fixed minimal cuff pressure (20 mm H2O) is an ideal and reliable technique in reducing the post-operative complications along with maintenance of hemodynamic parameters.&#x0D;

Effect of Early Balloon Inflation of Balloon Guide Catheter in Mechanical Thrombectomy for Large Vessel Occlusion.

A balloon guide catheter (BGC) is widely used in mechanical thrombectomy (MT). However, the balloon inflation timing of BGC has not been clearly established. We evaluated whether balloon inflation timing of BGC affects the results of MT. Patients who underwent MT with BGC for anterior circulation occlusion were enrolled. Patients were dichotomized into early and late balloon inflation groups, according to the timing of BGC inflation. Angiographic and clinical outcomes were compared between the two groups. Multivariable analyses were performed to evaluate the predictive factors for first-pass reperfusion (FPR) and successful reperfusion (SR). Of 436 patients, the early balloon inflation group showed a shorter procedure time (21 min [11-37] vs. 29 min [14-46], P = 0.014), a higher rate of SR with aspiration only (64.0% vs. 55.4%, P=0.016), a lower aspiration catheter delivery failure rate (11.1% vs. 19.4%, P = 0.005), less frequent technique conversion (36.0% vs. 44.5%, P = 0.009), higher rate of FPR (58.2% vs. 50.2%, P = 0.011), and a lower rate of distal embolization (7.9% vs. 11.7%, P = 0.006), compared to the late balloon inflation group. In multivariate analysis, early balloon inflation was an independent predictor for FPR (odds ratio, OR 1.53, 95% confidence interval, CI 1.37-2.57; P = 0.011) and SR (OR 1.26, 95% CI 1.18-1.64; P = 0.018). Early balloon inflation of BGC enables an effective procedure than late balloon inflation. Early balloon inflation was associated with higher rates of FPR and SR.

Choosing the right treatment for the right lesion, Part II: a narrative review of drug-coated balloon angioplasty and its evolving role in dialysis access maintenance.

Drug-coated balloons (DCBs) seek to inhibit restenosis in treated hemodialysis access lesions by delivering an anti-proliferative agent (paclitaxel) into the vessel wall. While DCBs have proven effective in the coronary and peripheral arterial vasculature, the evidence for their use in arteriovenous (AV) access has been less robust. In part two of this review, a comprehensive overview of DCB mechanisms, implementation, and design is provided, followed by an examination of the evidence basis for their use in AV access stenosis. An electronic search was performed on PubMed and EMBASE to identify relevant randomized controlled trials (RCTs) comparing DCBs and plain balloon angioplasty from January 1, 2010 to June 30, 2022 published in English. As part of this narrative review, a review of DCB mechanisms of action, implementation, and design is provided, followed by a review of available RCTs and other studies. Numerous DCBs have been developed, each with unique properties, although the degree to which these differences impact clinical outcomes is unclear. Target lesion preparation, achieved by pre-dilation, and balloon inflation time have proven important factors in achieving optimal DCB treatment. Numerous RCTs have been performed, but have suffered from significant heterogeneity, and have often reported contrasting clinical results, making it difficult to draw conclusions on how to implement DCBs in daily practice. On the whole, it is likely there is a population of patients who benefit from DCB use, but it is unclear which patients benefit most and what device, technical, and procedural factors lead to optimal outcomes. Importantly, DCBs use appears safe in the end-stage renal disease (ESRD) population. DCB implementation has been tempered by the lack of clear signal regarding the benefits of DCB use. As further evidence is obtained, it is possible that a precision-based approach to DCBs may shed light onto which patients will truly benefit from DCBs. Until that time, the evidence reviewed herein may serve to guide interventionalists in their decision making, knowing that DCBs appear safe when used in AV access and may provide some benefit in certain patients.
