HPB SO06 - An advanced clinical practitioner (ACP) led pancreatic cyst surveillance programme

Abstract Background The prevalence of pancreatic cysts (PCs), including intraductal papillary mucous neoplasms (IPMNs), has increased substantially over recent decades. This rising prevalence is due largely to the increasing volume and quality of medical imaging technology. Although PC's are often an incidental finding in asymptomatic individuals, a small number do harbour a certain malignant potential and thus raise warranted concern. The challenge therefore is identifying the high-risk lesions for early resection through robust, guideline-driven surveillance. To ensure a consistent and evidence-based approach to PC surveillance, our trust has adopted a dedicated surveillance programme led by an Advanced Clinical Practitioner (ACP) in gastroenterology. Method A PC surveillance clinic was designed and delivered from April 2023. The service underwent a formal inauguration and was promoted at the regional HPB MDT. All patients receive a standardised approach to surveillance in-line with the current international guidelines or regional MDT recommendation. Surveillance diagnostics are arranged by the ACP and patients are updated with regard to their results and next steps during a telephone or face-to-face consultation. A robust database was designed to capture relevant patient details and serve as a future research aid. Results 144 referrals have been received (04/23-04/24). 134 are undergoing surveillance, with discontinuation due to frailty, patient choice, diagnosis of an inflammatory cyst or relocation in 10 cases. Most PCs under surveillance are side-branch IPMNs (70.9%). Malignant transformation has not yet been observed, however 18 cases display worrisome features and 3 have high-risk stigmata. These are undergoing intensive surveillance or awaiting MDT discussion. 93% of surveyed patients (16) report a greater sense of involvement in their PC surveillance and a greater awareness of their surveillance protocol (93%). Referrer feedback (7) has been positive and staff are satisfied with this service (100%). Conclusion Robust surveillance of patients with PC will likely improve early detection and prognosis of pancreatic cancer by enabling early identification of resectable cases. A centralised service that adopts a single agreed guideline will reduce variation in the management of these cysts, ensure these complex lesions are under specialist observation and offer a single point of contact which will improve retainment and follow-up of these patients. It is intended that synchronous data collection will serve to generate a comprehensive repository of information relating to PC. This databases will aid future research into this evolving field and steer future guideline development.

The Effects of COVID-19 on Antifungal Prescribing in the UK—Lessons to Learn

Fungal infections are increasingly prevalent; however, antifungal stewardship attracts little funding or attention. Previous studies have shown that knowledge of guidelines and scientific evidence regarding antifungals is poor, leading to prescribing based on personal experiences and the inherent biases this entails. We carried out a retrospective study of inpatient antifungal usage at two major hospitals. We assessed the longitudinal trends in antifungal usage and the effect of COVID-19 on antifungal prescription, alongside levels of empirical and diagnostically targeted antifungal usage. Our results showed that the longitudinal patterns of total systemic antifungal usage within the trusts were similar to national prescribing trends; however, the composition of antifungals varied considerably, even when looking exclusively at the more homogenous group of COVID-19 patients. We showed a high level of empirical antifungal use in COVID-19 patients, with neither trust adhering to international recommendations and instead appearing to follow prior prescribing habits. This study highlights the significant challenges to optimise antifungal use with prescribing behaviour largely dictated by habit, a lack of adherence to guidelines, and high rates of empirical non-diagnostic-based prescribing. Further research and resources are required to understand the impact of antifungal stewardship on improving antifungal prescribing behaviours in this setting and the effects on outcome.

Proton pump inhibitors in inpatients: Are we getting it right? A retrospective analysis

Background: Proton pump inhibitors (PPIs) are commonly prescribed to hospitalized patients, but many of these prescriptions may not be based on evidence-based indications. It’s important to understand that inappropriate prescribing of PPIs can lead to unnecessary medications and financial burdens. Unfortunately, there are not many recent studies exploring how often PPIs are prescribed and if they are being prescribed appropriately. Objective: The study aimed to assess the appropriateness of PPIs use among hospitalized patients. It evaluated the indications for PPIs use and determined whether the use of PPIs in hospitalized patients is justified or not. Setting: The study was conducted at Hamad General Hospital, a tertiary academic healthcare center in the state of Qatar. Methods: A retrospective observational study with 201 subjects, was conducted in general internal medicine wards at a tertiary hospital. Physician documentation and inpatient and outpatient medication prescriptions were analyzed for PPIs exposure. Main outcome measures: The appropriateness of exposure to PPIs is determined based on international recommendations. Results: Of 533 hospitalized patients who were not critically ill, 201 (37.7%) were prescribed PPIs. The study found that 65.2% of the patients had no valid indication for PPIs exposure. Furthermore, 18% of patients were inappropriately prescribed stress ulcer prophylaxis with PPIs even though they had a low risk for the development of ulcer disease. After discharge, 82.6% of patients were prescribed PPIs, with the most common indication (43%) being gastrointestinal ulcer prophylaxis. Conclusion: This study sheds light on the issue of overutilization of PPIs, specifically in non-critically ill hospitalized patients. It highlights the unnecessary continuation of PPI prescriptions at discharge and emphasizes the importance of physicians reevaluating PPI prescriptions periodically to ensure they are still necessary and discontinuing them when possible to avoid unwanted consequences.

Protecting the protectors: redefining immunity protections for National Human Rights Institutions

ABSTRACT National Human Rights Institutions (NHRIs) established pursuant to the United Nations Paris Principles play a crucial role in protecting human rights at the domestic level, but they face significant risks of interference and obstruction when carrying out their sensitive functions. International standards recommend that NHRIs’ enabling legislation includes functional immunity provisions to protect them from these risks to their independence and effectiveness. However, presenting the results of the first comprehensive analysis of the functional immunity protections for NHRIs across 111 countries, this article finds that 40% of NHRI laws lacked any such protection provisions, while the remaining provisions were of questionable quality. To protect NHRIs from interference and obstruction, this article proposes a redefinition and strengthening of NHRI functional immunity provisions based on an analysis of existing protection provisions, international recommendations, and comparable immunity protections for judges and parliamentarians. It proposes a new framework for functional immunity that aims to grant NHRI leadership and staff the necessary level of protection against interference and obstruction, which also has wider relevance for other similar domestic bodies.

What are the minimal criteria of goal-directed perfusion (GDP) in adult cardiac surgery?

Introduction: Nowadays, many cardiac surgery teams are adopting the goal-directed perfusion (GDP) strategy in their practice to maintain optimal perfusion during cardiac surgeries and improve patient outcomes. Furthermore, it plays an indispensable role as a quality control tool to monitor both perfusionists’ practice and equipment (in addition to disposables used in the surgery. Objectives: To identify the role and the elements of GDP that facilitate better surgical outcomes. In addition, to compare between GDP and the traditional conventional perfusion strategy (CP) in terms of perfusion adequacy and surgical outcomes. Finally, to recognize challenges that may prevent the effective application of GDP and finding possible applicable solutions. Methods: A systematic literature review was conducted from three different databases PubMed, SpringerLink, and ScienceDirect. The selected studies were in English from the USA and Europe with a time frame starting from 2005. Results: The findings highlight the crucial role of the GDP strategy in protecting and preserving end-organ function after on-bypass cardiac surgery procedures. Furthermore, a clear understanding of the GDP implementation component and criteria was obtained. Alternatively, a satisfactory GDP level can be achieved by the optimal utilization of available resources. Discussion: Dismantling the GDP strategy into practically recognized components to ease the implementation at different levels of perfusion practice. Conclusion: The GDP approach involves the intensive monitoring of respiratory-related parameters to enhance surgical outcomes. The process includes blood preservation, optimal flow and intraoperative parameters management. Monitoring is the key element of GDP, which can be applied by using the sophisticated technology or the proper use of existing resources to develop protocols within the international guidelines and recommendations. Achieving an optimal perfusion requires concerted efforts of organizational, safety, and practical measurements.

Recognition and Management of Postpartum Hemorrhage

Abstract Postpartum hemorrhage (PPH) is an obstetric emergency and refers to excessive blood loss after birth. Loss of blood volume and oxygen-carrying capacity may lead to maternal hypovolemia and hypotension resulting in tissue hypoxia, the onset of anaerobic metabolism, and multiorgan failure. If timely and appropriate action is not taken, cardiac arrest and maternal death may occur. If the amount of blood loss exceeds 500 mL following a vaginal birth or 1000 mL during or following a cesarean section, it is termed PPH. Similar to any other surgical hemorrhage, PPH is classified into primary PPH (occurs within 24 hours of birth) or secondary PPH (between 24 hours and 12 weeks postpartum). PPH is a major contributor to maternal deaths worldwide, and it is estimated that a person dies because of PPH approximately every 5 minutes. Therefore, measures should be directed at prevention and early detection of PPH with prompt management. The prevalence of PPH varies globally and is influenced by location, socioeconomic factors, and the availability and quality of health care. The World Health Organization reported that PPH accounts for a quarter of global maternal deaths. The Mothers and Babies Reducing Risks through Audits and Confidential Enquiries report from the United Kingdom (2023) highlighted that despite rare mortality due to hemorrhage, the number of people dying of obstetric hemorrhage is not decreasing, particularly among people with abnormally invasive placentation. Additionally, substandard care was found to be responsible for more than 50% of deaths due to PPH in the United Kingdom. Therefore, it is vital that adequate healthcare infrastructure, trained and competent healthcare professionals, and immediate access to resources, interventions, and multidisciplinary teams are essential both in well-resourced and resource-restrained healthcare systems. Healthcare professionals must identify the potential risk factors for PPH and initiate preventive measures whenever possible. Additionally, they must respond swiftly if PPH occurs and ensure a multidisciplinary, multilayered approach for a synchronized response to optimize outcomes. This review article emphasizes the etiopathogenesis, diagnosis, and management of PPH based on current scientific evidence as well as international best practice recommendations.

Management of Adult Patients with Newly Diagnosed or Relapsed Primary Immune Thrombocytopenia in Eastern Austria.

Treatment sequence in primary immune thrombocytopenia (ITP) is based on national and international recommendations, treatment availability, and physician expertise. This article aimed to provide real-world data on treatment sequence and responses to first- and second-line treatments in newly diagnosed and relapsed adult ITP patients. We analyzed a cohort of 46 adult ITP patients from the Vienna ITP Biobank, who started first-line therapy within 1 week before their first study visit between February 2016 and March 2023. We investigated clinical patient characteristics and patient management in our specialized center and examined the impact of the international ASH guidelines on ITP treatment. Forty-six primary ITP patients, 27 (58.7%) with newly diagnosed ITP and 19 (41.3%) with relapsed ITP, were investigated. Most patients were female (65.2%) with a median platelet count of 9 × 109/L, and 31 patients (67.4%) had bleeding symptoms. All patients received first-line treatment with oral prednisolone; 15 patients received oral prednisolone combined with intravenous immunoglobulins (IVIGs), which were more commonly administered in newly diagnosed than in relapsed ITP patients. First-line therapy resulted an overall response in 82.6% of patients after a median (interquartile range [IQR]) time of 10 (5-25) days. There was no difference in treatment responses between newly diagnosed and relapsed ITP patients, but newly diagnosed patients had a shorter time to response (median [IQR]: 8 [5-14] and 14 [8-27], p = 0.02). Twenty-three (50%) of the patients (11/27 newly diagnosed [40.7%], 12/19 relapsed [63.2%]) required second-line ITP therapy. Thrombopoietin-receptor agonists (TPO-RAs) were the most commonly used second-line therapy with a response rate of 73.7%, and a median (IQR) time to treatment response of 15 (12-20) days. Overall response rates to TPO-RA treatment did not differ between newly diagnosed and relapsed ITP. Following the publication of novel guidelines in 2019, the median (IQR) duration of corticosteroid treatment shortened (100-52 days, p = 0.01), as did the time to second-line treatment (160-47 days, p = 0.01), and the median number of first-line therapies decreased from 2 (1-3) to 1 (1-2). Initial treatment with corticosteroids was effective in the majority of newly diagnosed and relapsed ITP. Response rates to initial corticosteroid treatment in ITP patients are consistent with previous data, but only 50% achieve sustained remission. TPO-RAs, which are well tolerated and effective, are the most commonly used second-line therapy in our study population. International guidelines have led to faster treatment transitions and reduced splenectomy rates. Integration of real-life experience, expert consensus, and guidelines optimizes ITP patient management.

Existing Health Inequities in the Treatment of Advanced and Metastatic Cancers.

This study aims to identify health inequities related to the medical treatment and supportive care of patients with advanced/metastatic cancer and recommend solutions to promote health equity. Despite robust strides in the development of therapeutic strategies for advanced and metastatic cancer, significant disparities in treatment access and implementation exist. Race, socioeconomic status, gender, and geography represent just a few of the individual-level factors which contribute to challenges in treatment administration, thorough evaluation of germline genetics and tumor genomics, and quality palliative and end-of-life care. Given the increasing complexity of cancer treatments and our enhanced understanding of tumor biology, efforts to uniformly provide equitable and high-level care to all patients are needed. In this review we will discuss factors that contribute to health inequities in patients with advanced and metastatic cancer diagnoses, highlighting opportunities for intervention, ongoing challenges in change implementation, and national and international society recommendations to eliminate disparities. Acknowledging existing inequities and engaging in multilevel discourse with key stakeholders is needed to optimize care practices to the benefit of all patients.

Literature review, surgical decision making algorithm, and AGREE II-S comparison of national and international recommendations and guidelines in pelvic organ prolapse surgery.

The average lifespan has increased over time due to improvements in quality of life, leading to an aging population that stays healthy for longer. Pelvic organ prolapse (POP), whether uterine or vaginal, is a problem that severely impairs quality of life and imposes significant restrictions. The present study provides the reader with a summary of the many surgical techniques used in POP surgery, comparing international guidelines, offering an algorithm that is simple to understand, and allows the reader to quickly choose the table that includes the best surgical therapy for each individual. Using relevant keywords, the writers searched the PubMed and Scopus databases for relevant publications from 2000 to April 2023. Studies with cases of oncologic disorders or prior hysterectomy performed for another reason were not included in the analysis. Ten distinct international guidelines are highlighted and examined in the present study. We used the Appraisal of Guidelines for Research and Evaluation II-S (AGREE II-S) method to assess their quality, and incorporated the results into the conclusion. Worldwide, anterior colporrhaphy is the preferred method of treating anterior compartment abnormalities, and mesh is virtually always used when recurrence occurs (which happens in about half of the cases). Worldwide, posterior colporrhaphy is commonly used to repair posterior compartment abnormalities. Only a few national guidelines (the Iranian guideline, Acta Obstetricia et Gynecologica Scandinavica [AOGS], and the German-speaking countries) permit the use of mesh or xenograft in cases of recurrence. There is agreement on the abdominal approach (sacrocolpopexy) with mesh for treating apical deformities. Sacrospinous-hysteropexy is the standard method used to guide the vaginal approach; mesh is typically used to aid in this process. There are just three recommendations that do not include vaginal operations: HSE, AOGS, and Iran. Of obliteration techniques, colpocleisis is unquestionably the best. In conclusion, our analysis highlights the significance of customized methods in POP surgery, taking into account the requirements and preferences of each patient. To choose the best surgical therapy, criteria and patient features must be carefully considered.

Non-Invasive Therapeutic Approaches for Mechanical Low Back Pain: An Integrative Systematic Review

Background: Mechanical low back pain (LBP) is one of the most prevalent musculoskeletal conditions, affecting a significant portion of the global population at some point in their lives. It is characterized by pain in the lumbar region without an obvious inflammatory or infectious origin, typically exacerbated by movement, posture, or mechanical load. LBP, whether acute, subacute, or chronic, is a leading cause of temporary and permanent disability, with significant economic repercussions due to lost workdays and healthcare costs. Recent clinical guidelines, such as those from the American College of Physicians (ACP) and the National Institute for Health and Care Excellence (NICE), emphasize the importance of non-invasive interventions for managing mechanical LBP, particularly in acute and chronic cases. In this context, this systematic review aims to consolidate current evidence on available therapeutic interventions, focusing on non-invasive treatments. Objective: To evaluate the available evidence on non-invasive therapeutic interventions for the treatment of mechanical low back pain. The review aims to synthesize international clinical guideline recommendations and identify the most effective practices for reducing pain and improving functional outcomes. Methods: This review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Randomized controlled trials, systematic reviews, and clinical guidelines published up to 2023 addressing the management of mechanical low back pain in adults were included. Databases such as PubMed, Cochrane Library, and grey literature sources, including guidelines from medical societies, were searched. The study selection process followed strict eligibility criteria, including publications in English and Portuguese focused on non-invasive treatments for LBP. The methodological quality of the studies was assessed using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) tool. A total of 15 studies met the inclusion criteria, covering a range of non-invasive interventions such as physical therapy, exercise, acupuncture, manual therapy, and pharmacological approaches. Results: Evidence suggests that exercise-based interventions, particularly programs focused on muscle strengthening and stretching, are effective in reducing pain and improving functional outcomes in patients with mechanical LBP. Manual therapies and acupuncture also demonstrated benefits, albeit with less robust evidence. Reviewed guidelines recommend caution in the use of pharmacological interventions, such as nonsteroidal anti-inflammatory drugs (NSAIDs), particularly in chronic cases. Conclusion: This review highlights that non-invasive therapies, especially supervised exercise programs, represent the most effective and safe treatment for mechanical low back pain. The revised international guidelines reinforce the importance of avoiding early invasive interventions, except in cases of persistent or refractory pain. Appropriate management of mechanical LBP should be individualized, integrating evidence-based interventions to promote functional rehabilitation and minimize the impact of pain on patients' quality of life.

Portuguese translation, cultural adaptation and psychometric properties of the temporomandibular joint scale: a cross-sectional study

BackgroundThe temporomandibular joint (TMJ) scale assesses the severity of temporomandibular joint disorders (TMD), yet a European Portuguese translation is lacking.ObjectivesTo translate, cross-culturally adapt and to examine the psychometric properties (construct validity and reliability) of the TMJ scale.MethodsTranslation and cultural adaptation were carried out according to international recommendations, including initial translation, evaluation of this translation and cultural adaptation by a panel of experts, and back translation. The final Portuguese version was used to examine the reliability and validity, and participants with TMD were recruited from a Portuguese outpatient clinic. Reliability measures included internal consistency with Cronbach’s alpha and test-retest reliability with the intraclass correlation coefficient (ICC2,1). The Spearman correlation comparing the TMJ scale with the Fonseca and Helkimo indexes was used to assess the construct validity.ResultsA total of 63 participants (23 ± 2 years; 61,9% female) were included. Similar internal consistency was observed between the two moments of application (0.921 and 0.918), and test-retest reliability was excellent, with an ICC2,1 = 0.998 (95%CI: 0.988–0.999). Robust positive correlations (rho 0.554–0.611, p < 0.001) were found between the TMJ scale and Fonseca and Helkimo indexes.ConclusionThe European Portuguese version of TMJ scale is now available to improve the assessment of severity of TMD in routine clinical practice. This version is also reliable and valid.

Capturing the incidence of patient agitation amongst conscious sedation ERCPs and the impact on therapeutic outcomes.

Completing advanced endoscopic procedures such as endoscopic retrograde cholangiopancreatography (ERCP) under conscious sedation is challenging. International recommendations favor enhanced sedation (e.g. propofol) for ERCP. Conscious sedation can result in sedation-related failure (SRF) and agitation for some patients, limiting therapeutic efficacy. The aim of this study is to establish the risk of SRF and the impact on therapeutic success under conscious sedation practice in a single tertiary referral center. A retrospective review of a prospectively maintained ERCP database, analyzing sedation, procedural success, and complications. Over 19 months, 807 conscious sedation ERCPs were recorded. Median midazolam dose was 5 mg (range 1-14 mg) and median fentanyl dose was 75 µg (0-200 µg). Sedation reversal was required in 0.1% of cases (1/807). Overall ductal cannulation rate was 92%. Severe agitation was recorded in 11% (86/807) of conscious sedation ERCP reports with SRF present in 3% (22/807). Patient agitation resulted in significantly lower cannulation (81% vs 92%, P = 0.002) and successful clearance rates (49% vs 85%, P = 0.002) versus non-agitated cases. Complication and pancreatitis rates were unaffected. Highest rates of SRF and agitation were identified in female patients, patients aged <50 years old, and post-operative biliary leak indications. Over 10% of conscious sedation ERCPs are compromised by sedation issues, resulting in procedure abandonment or significantly diminished therapeutic success. General anesthetic ERCP is beneficial in facilitating biliary access, removing the risk of agitation and providing stability to aid cannulation. Female patients, patients aged <50 years, and post-operative biliary leak ERCPs appear as the priority cases for enhanced sedation support.

Modeli organizacije paliativne oskrbe odraslih

Palliative care is a young medical profession in Slovenia. It ensures the best possible quality of life for patients with chronic incurable diseases, regardless of their age, and offers support to their loved ones during the patient’s illness and after death during the mourning period. In the early period, palliative care is integrated with specific treatment. However, later, it continues with the period of late palliative care and throughout the last days of life. Its central purpose is to preserve the dignity of life and the values of the individual. Contemporary guidelines envision the implementation of palliative care tailored to individual needs throughout the entire course of life with an incurable disease. It should be holistic, continuous, and integrated into core medical disciplines. The appropriate coordination of palliative care activities, which directs the patient to the most suitable provider based on their current needs is of key importance. In this paper, based on a review of international recommendations, local characteristics and experiences, we will present the most common palliative care activities, their interrelationship and interdependence in the provision of palliative care, and thus define a model of palliative care that can, in our environment, provide appropriate support to as many patients as possible.

Comparison of Physical Activity and Sedentary Behaviour Patterns by Sex, Geographical Location, and Time of the Week in Mexican Adolescents

Background: Excess sedentary behaviour (SB) and insufficient physical activity have been identified as risk factors for cardiometabolic diseases in adolescents, and some factors may affect how much time they spend on these activities. This study sought to compare the SB and PA patterns as well as compliance with PA recommendations by sex, geographical location, and time of the week in Mexican adolescents. Methods: In a cross-sectional design, we objectively assessed SB and PA in 106 adolescents (15 to 18 y) through waist-worn accelerometers for one week. The time spent in SB and in PA at different intensities was compared by sex, geographical location and time of the week with two-way and three-way repeated measures MANOVAs, while the compliance with physical activity recommendations (i.e., ≥60 min/day) was compared using chi-squared and McNemar tests. Results: Male participants spent more time in moderate, vigorous, and moderate to vigorous PA than females both during the whole week and on weekdays (all p &lt; 0.05). There was no significant difference in SB nor PA by geographical location (i.e., metropolitan vs. non-metropolitan areas). Moreover, all participants spent more time on moderate, vigorous, and moderate to vigorous PA on weekdays than on weekends (p &lt; 0.05). Compliance with international PA recommendations also showed a sex difference (males &gt; females) and change between weekdays and weekends with no difference by geographical location. Conclusions: While geographical location does not seem to be a relevant factor, sex and time of the week appear to influence the SB and PA patterns in Mexican adolescents.

Biofeedback system in remotely monitored exercise program in pregnant women with obesity: a pre-experimental research

Objectives: E-health programs may be an excellent strategy to overcome some barriers related to the non-practice of exercise among pregnant women with obesity. This study aims to present a monitored exercise program for pregnant women with obesity using the Sword Phoenix® biofeedback system; and to evaluate pregnant women's perception of the biofeedback system and the exercise program protocol. Methods: A pre-experimental research was done through a One-shot case study design. Twelve pregnant women with Body Mass Index ≥ 30 kg/m2, were invited to perform for two weeks a home-based structured exercise program protocol with a digital biofeedback system, during exercise the women used an accelerometer to measure the intensity of the exercises. At the end of the two-week exercise period, the pregnant women filled in a questionnaire to assess their perception of usability, satisfaction, safety and motivation regarding exercise program and biofeedback system. Results: The accelerometry results indicate that, during the exercise program protocol, the pregnant women spent 79.3% of the time in moderate activities. The adherence to the program had an average performance of 40%. The results of the questionnaire demonstrated that 100% (n=12) of the participants enjoyed the system and recognized it as a safe instrument with the potential to increase physical activity during pregnancy. Discussion: The biofeedback system can be a useful tool for implementing an exercise program for pregnant women with obesity. The proposed exercise program complies with international recommendations for physical exercise during pregnancy, ensuring safety. Additionally, it reduces the team intervention, increases participant motivation, and has the potential to reduce sedentary behavior in pregnant women with obesity.

Nonlinear correlation between serum vitamin D levels and the incidence of endometrial polyps in infertile women.

Are serum vitamin D levels associated with the incidence of endometrial polyps (EPs) in infertile patients? Serum 25(OH)D levels were nonlinearly correlated with the incidence of EPs in infertile women. EPs are a common condition that may affect the receptivity of the endometrium in women of reproductive age. Vitamin D regulates cell proliferation and differentiation, apoptosis, angiogenesis, anti-inflammation, and immunomodulation, in addition to its well-known functions in balancing calcium and phosphorus. Previous studies have shown that vitamin D concentrations are associated with reproductive outcomes, and that low vitamin D levels are associated with the incidence of colorectal polyps and nasal polyps. There is little evidence regarding the relationship between EPs and serum vitamin D levels. We conducted a cross-sectional study using data from Guangdong Women and Children Hospital from January 2019 to October 2023, enrolling 3107 patients. A total of 3107 infertile patients who underwent hysteroscopy were included in this study; 642 patients had endometrial polyps and 2465 had a normal uterine cavity. Hysteroscopy findings included risk of EPs, polyp size, percentage of multiple polyps, and incidence of chronic endometritis (CE). Serum vitamin D were assessed by measuring total 25(OH)D using chemiluminescence. According to international guideline recommendations for vitamin D deficiency, patients were divided into two groups: the <50 nmol/l group and the ≥50 nmol/l group. Univariable and multivariable logistic regression models, stratified analyses, and smooth curve fitting were used to examine the relationship between serum 25(OH)D levels and risk of EPs. Of all patients, 23.8% (740/3107) were vitamin D deficient (<50 nmol/l). The incidence of EPs was significantly higher in the 25(OH)D < 50 nmol/l group than in the ≥50 nmol/l group (24.9% vs 19.3%; P = 0.001). However, there were no differences in polyp size, proportion of multiple polyps, and presence of CE between the two groups. After controlling for confounders, 25(OH)D ≥ 50 nmol/l (compared with <50 nmol/l) was negatively associated with risk of EPs (adjusted OR, 0.733; 95% CI, 0.598-0.898). Other variables that had an impact on polyp incidence included BMI, type of infertility, CA125, and CD138-positive plasma cells. In addition, a linear regression model between age and serum 25(OH)D levels showed a positive linear association. Subgroup analyses were performed for different age groups, and the risk of EPs was significantly higher in the 25(OH)D < 50 nmol/l group than in the ≥50 nmol/l group, both in the younger subgroup (23.8% vs 19.1%) and in the older subgroup (28.0% vs 19.9%). The smooth curve fitting model showed a nonlinear correlation between 25(OH)D levels and risk of EPs (nonlinear P-value = 0.020), with an optimal threshold of 51.8 nmol/l for 25(OH)D levels. Moreover, subgroup smooth curve fitting models showed a nonlinear correlation between 25(OH)D levels and polyp risk in patients aged <35 years (nonlinear P-value = 0.010), whereas a linear correlation between 25(OH)D levels and polyp risk was found in patients aged ≥35 years (nonlinear P-value = 0.682). Caution should be exercised in interpreting our findings as this is a correlational study and causality cannot be inferred from our results. In addition, because of strict inclusion and exclusion criteria, our results may not be generalizable to unselected populations, including premenopausal women or women of other races. This study demonstrated for the first time that vitamin D deficiency is an independent risk factor for the incidence of EPs in infertile patients. Identifying modifiable risk factors (e.g. vitamin D deficiency) can help in the development of new strategies for treating polyps or to protect against polyp development. Further clinical intervention trials and laboratory studies are needed to evaluate the effect of vitamin D on the development of EPs and to elucidate the mechanisms. The study was funded by the National Natural Science Foundation of China (82101718) and Natural Science Foundation of Guangdong Province, China (2022A1515010776). No competing interest was involved in this study. N/A.

Performance variables and nutritional status analysis from Moroccan professional and adolescent football players during the competition period: a descriptive study.

Nutrition plays an integral role in optimizing football players' performance during training sessions and matches and maintaining their overall health throughout the season. This study aimed to evaluate how well the dietary practices of professional and adolescent football players in Morocco during the competitive period met international macronutrient recommendations, and to explore the relationship between their nutritional status and aerobic performance, as measured by the Yo-Yo IRL1 test. A total of 277 footballers from Morocco's professional league, "Botola-Pro", were monitored over a seven-day (training microcycle) during the competitive period. The dietary intake was assessed through self-reported methods and 24-hour recalls. Relevant body composition was measured with bioelectrical impedance (BI), and aerobic performance was evaluated using the Yo-Yo IR test. The results indicated significant variations in performance and nutritional status across different categories and age groups. The nutritional status of the players didn't match the UEFA recommendations (p < 0.001). We found that higher intake levels of carbohydrates and proteins were positively correlated with the total distance covered by the players (p < 0.001, r = 0.63, R2 = 0.4 for carbohydrates; p < 0.001, r = 0.59, R2 = 0.35 for proteins). Conversely, a higher proportion of energy derived from fats in the diet was negatively correlated with the distance covered (p < 0.001, r = -0.64, R2 = 0.41). These findings suggest that optimizing carbohydrates and protein intake while managing fat consumption is crucial for enhancing sporting performance. This information is essential for tailoring training programs and nutritional regimens based on the competition level.

Hospital satisfaction among older adults by European Union health system clusters

Abstract Background Health systems are influenced by political, historical, cultural and socio-economic factors and differ across countries. Classification of EU health systems into 5 clusters has allowed for international comparison and policy recommendations. This study is based on the Andersen’s Behavior Model, that predicts that a sequence of predisposing, enabling and need factors influence satisfaction and utilization of healthcare services. Aim Examine the nature and relationship of predisposing, enabling and need factors associated with hospital satisfaction of older adults across EU nations by health system classification clusters. Methods Data from Wave 9, of the Survey of Health, Ageing and Retirement in Europe (SHARE) were examined using a sample of older adults from 10 EU countries. Analysis: Non-parametric one-way ANOVA (Kruskal- Wallis test) and Multinominal Logistics regression were performed to test the null hypothesis that (1) hospital satisfaction is equal across all clusters, and (2) predisposing, enabling, and need factors, are not predictors of hospital satisfaction. Findings There was a statistically significant difference in hospital satisfaction by cluster [Chi Square= 231.44, df = 21; p&amp;lt; .001]. Age, mental health, technology and chronic disease are predictors of healthcare facilities satisfaction. [Chi Square 50.94, df = 3, p&amp;lt; .001], Among those that reported to be highly unsatisfied with healthcare facilities, [chronic disease (Beta = -2.64) and mental health (Beta = -4.41) df = 1 p&amp;lt; .001] significantly predicted hospital satisfaction. Implications for Policy and Practice: Initiatives for the care of older adults should not only aim to increase access to care but also provide targeted services for sub populations such as older adults with mental health and chronic diseases. Further, significant investment is required in technology infrastructure within hospitals and technological assistance or training should be provided to older adults. Key messages • Older adults satisfaction with hospitals varies by health system clusters and is predicted by age, mental health, use of technology and chronic disease. • Chronic disease and mental health are strong predictors of hospital dissatisfaction among older adults.

Echocardiographic and clinical features of patients developing prosthesis-patient mismatch after TAVI: insights from an international multicenter registry

Abstract Background The impact of prosthesis-patient mismatch (PPM) after transcatheter aortic valve implantation (TAVI) is controversial. Purpose Our study aims to evaluate the impact of PPM on mortality and clinical-echocardiographic progression of cardiac damage in a "real world" cohort of patients at intermediate and low surgical risk and to characterize its main predictors. Methods 963 patients who underwent TAVI procedure between 2017 and 2021, from an international multicenter observational registry, were included in this analysis. Multiparametric echocardiographic data were analyzed at 1-year follow-up (FU). Clinical and echocardiographic features were stratified by presence of PPM and PPM severity, as per the most current international recommendations (VARC-3 criteria). Results 18% of patients developed post-TAVI PPM, (7.7% of the whole cohort severe). At baseline, 50.3% of patients with PPM were male (vs 46.2% in the cohort without PPM, p=0.33), aged 82y (interquartile range (IQR) 79-85y) vs 82y (IQR 78-86y; p=0.46), and 55.6% had Balloon-Expandable valves implanted (vs 46.8% of patients without PPM, p=0.04); they had smaller left ventricular outflow tract (LVOT) diameter (20mm, IQR 19-21 vs 20mm, IQR 20-22, p=0.02), reduced Stroke Volume index (SVi) (34.2 vs 38 ml/m2, p&amp;lt;0.01) and transaortic flow rate (190.6 vs 211 ml/s, p&amp;lt;0.01). At pre-discharge FU patients with PPM had more paravalvular aortic regurgitation (AR) (moderate/severe AR 15.8% vs 9.2%, p&amp;lt;0.01). At a median FU of 1.46 years (IQR 1-4), there was no evidence of a significant impact of PPM on overall mortality (15.3% vs 13.1%, p=0.46) nor on rehospitalization rate for heart failure (4.3% vs 8.0%, p=0.10). At 1-year FU, maladaptive alterations of left ventricular parameters were found in patients with PPM, with a significant increase in endsystolic diameter (ESD) (33 vs 28mm, p=0.03) and a statistically non-significant increase in LV mass index (121 vs 106g/m2, p=0.07). Interestingly, trajectory parameters of patients with PPM from baseline to 1-year FU showed a reduced cardiac remodeling compared to patients without PPM, including no LVEF improvement (p=0.88), absent reduction of LV end-diastolic volume (p=0.70), indexed LV mass (p=0.31), ESD (p=0.48) and pulmonary artery systolic pressure (p=0.82), and an increase of basal RV diameter (p&amp;lt;0.001). Patients with moderate/severe PPM had worse NYHA functional class at 1 year (NYHA III-IV 13% vs 7.8%, p=0.03). Independent predictor of PPM at multivariable logistic regression was male gender (OR=1.93, p=0.04); while SVi (OR=0.86, p&amp;lt;0.001), prosthetic size &amp;gt;23mm (OR=0.62, p=0.03) and LVOT diameter (OR=0.79, p=0.02) had protective effect. Conclusions There was no evidence of a short- or medium-term impact of PPM on mortality. However, clinical-echocardiographic evaluations demonstrated a PPM-related pattern of early ventricular maladaptive alterations associated with a significant deterioration in NYHA class at 1 year.

Characterization of X-ray Beams: Determination of K\(_{a,e}\) for Comparison with DRLs

Aims: The aim of this experimental study was to quantify the entrance surface air kerma (Ka,e) of X-ray beams in radiographic examinations, and the obtained values were compared with national and international Diagnostic Reference Levels (DRLs). Place and Duration of Study: Sample: Department of Medical Physics and Radiology, Franciscan University (UFN), between June 2023 and August 2024. Methodology: Initially, the main quality control (QC) tests were applied to characterize the radiographic equipment. During the evaluation of the X-ray beam, a dosimetric set was used, and for the same QC geometry, Air Kerma Rate (KAIR) measurements were obtained to determine the output of the X-ray tube. Under the same conditions, a phantom without water and the same filled with water were used to determine the backscatter factor (BSF), which was then used to estimate the Ka,e for the main radiographic examinations. Results: The results of this study are consistent with other studies and identified the region/anatomy with the highest radiation exposure, highlighting the importance of its optimization and verifying that continued professional training should be integrated into best practices to ensure greater safety in procedures. The results obtained evidence the necessity for adjustments in image acquisition protocols, as the Ka,e values found in this study, although within the limits established by the national DRLs, exceed the reference values of countries such as the United Kingdom and Japan in the areas of the skull, abdomen, and lumbar spine. This discrepancy highlights the importance of the periodic review and update of DRLs, in accordance with international recommendations and the technological evolution of equipment. Dose optimization is an ongoing process that involves the evaluation of image quality, the appropriate selection of technical parameters, and the implementation of specific dose protocols. The continuous training of radiology professionals is essential to ensure the correct application of imaging techniques and the minimization of patient exposure to ionizing radiation. Conclusion: This study shows the importance of evaluating radiation dose in diagnostic imaging and the need for a multidisciplinary approach to dose optimization. Implementing quality assurance programs, updating DRLs, and providing ongoing training for professionals are essential to ensure patient safety and high-quality diagnostic imaging. The methodology adopted in this study can contribute to the ongoing education of radiology professionals, promoting the correct application of imaging techniques and reducing patient exposure to ionizing radiation.
