Background Over the past few decades, World Health Organization (WHO) has made massive efforts to promote the development of a vaccine against Lassa virus (LASV), one of the top ten priority pathogens for research and development under the WHO R&D Blueprint for Emerging Infections. To date, several vaccines are at different stages of development. In this scenario, a validated and standardised assay to measure LASV neutralising antibodies is urgently needed for vaccine development and comparison. Methods The neutralisation assay remains the gold standard for determining antibody efficacy. Here we have proposed a safe and validated pseudotyped neutralisation assay for LASV, taking advantage of the development of the first WHO International Standard and Reference Panel for Anti-Lassa Fever (NIBSC code 21/332). Results and Conclusions The proposed results demonstrate that the pseudotyped luciferase neutralisation assay is a specific serological test for the measurement of LASV neutralising antibodies without cross-reacting with standard sera specific for heterologous viral infections. In addition, the assay is accurate, precise, and linear according to criteria and statistical analyses defined and accepted by international guidelines.

Rainwater harvesting (RWH) systems offer an opportunity to diversify the water matrix under drought scenario. However, there is not a robust institutional framework for managing this new source of water. The objective of this study was to evaluate the influence of the catchment surface material on the quality of rainwater collected. Three systems were installed in south-central Chile, which collected rainwater from three different surfaces: gravel tile, zinc-polycarbonate sheets, and clay tiles. The RWH system consists of a first flush diverter and then a storage system with chlorination. The rainwater was characterized by its physicochemical and microbiological properties for its possible final use, considering the current regulations for drinking water and agricultural irrigation. The results indicate that the raw rainwater harvested from different surfaces presented a high mean conductivity of 232 ± 146 µS/cm. Meanwhile, fecal coliform values were <1 MPN/100 mL, which indicates good microbiological quality. Regarding the quality for use as drinking water, it was found that of 39 parameters evaluated according to a reference standard, only the pH was above the indicated limit. Meanwhile, the harvested water presents satisfactory quality for irrigation, except for its sodium (35–50% above the standard) and pesticide values (with respect to 0.028 µg Delta-BHC/L at Site 2).

Pregnant women identified to carry hepatitis B surface antigen (HBsAg) should be linked to care for the determination of the need for long-term antiviral therapy (LTT). We assessed the performance of simplified criteria, free from HBV DNA quantification, to select women eligible for LTT using different international guidelines as a reference. A retrospective analysis of HBV-infected pregnant women enrolled in the phase 4 ANRS TA-PROHM study was conducted in Cambodia. Sensitivity, specificity, and AUROC were computed to compare three simplified criteria (TREAT-B, HBcrAg/ALT, and TA-PROHM) with the American (AASLD) and European (EASL) guidelines as a reference. An additional assessment was performed at 6 months postpartum. Of 651 HBsAg-positive women, 209 (32%) received peripartum antiviral prophylaxis using tenofovir disoproxil fumarate (TDF). During pregnancy, 9% and 12% of women were eligible for LTT according to AASLD and EASL guidelines, respectively; 21% and 24% of women were eligible for prophylactic TDF and 2% and 5% in those ineligible (p < 0.001). Using the AASLD guidelines, the AUROC of TREAT-B, HBcrAg/ALT, and TA-PROHM scores were 0.88 (95%CI, 0.85–0.90), 0.90 (95%CI, 0.87–0.92), and 0.76 (95%CI, 0.73–0.80), respectively. Using the EASL guidelines, the AUROCs were lower: 0.73 (95%CI, 0.69–0.76), 0.76 (95%CI, 0.73–0.80), and 0.71 (95%CI, 0.67–0.74), respectively. Among those ineligible for prophylactic TDF, only 2% to 6% present an indication for LTT at 24 weeks postpartum. Few pregnant women are eligible for LTT, and the use of simplified criteria could represent an efficient triage option in decentralized areas to identify those negative for whom there is no urgent indication for LTT and focus on those positive for whom other exams must be conducted to confirm LTT indication.

Background: Santha Chandrodaya Mathirai (SSM) [Cāntacantirōtaya māttirai] is a classical tablet formulation in Siddha medicine used in various types of fevers. Because of limited research validation in terms of the product compactness, quality and safety, the present study focuses on the formulation, characterization and standardization of the tablet dosage. The objective of the study is to prepare SSM as per Standard operating Procedures (SoPs) mentioned in classical text and to characterize it chemically using modern analytical techniques. Materials and Methods: The tablet dosage was prepared from the In-house R&D GMP Pharmacy facility of Siddha central research Institute and validated through analytical measures like pre-compression, post-compression parameters, physiochemical analysis, analytical studies like High Performance Thin Layer Chromatography (HPTLC), Special Edition Microscopy (SEM) with Energy Dispersive X-Ray (EDAX), Fourier Transform Infrared Spectroscopy (FT-IR) and UV Absorption Spectroscopy (UV-AS). Results: As per the reference standards, the mean flow property of the Tablet granules (31°) was fair enough, the mean compressibility index (17.3%) and Hausner's ratio (1.452) indicates its good flow character. The tablet passed the USP standards of weight variation in %. The friability test reported the maximum weight loss to be 0.06 %, a good acceptable value. The highest disintegration time was observed at 60 min. The samples were devoid of Heavy metals, microbial and aflatoxin contamination. At short UV of 254 nm, long UV of 366 nm, and post derivatized plate in white light there were observation of 6 spots, 8 spots and 12 spots respectively in TLC photo documentation. EDAX reported the presence of Carbon, Oxygen, Sodium, Chlorine, Potassium, and Niobium molecules in the sample with no traces of heavy metals. FTIR spectra showed three high peak areas at the range of band 2917.08, 2849.10, and at 1717.08 that corresponds to carboxylic acid, alkane bond, and a, ß-unsaturated ester. Conclusion: The In-house samples of SSM reported standard values in terms of quality and safety. Further clinical trials are warranted to validate its efficacy. [ABSTRACT FROM AUTHOR]

Introduction: Turner syndrome association with multi-organ system comorbidities highlights the need for effective implementation of follow-up guidelines. We aimed to assess the adequacy of care with international guidelines published in 2007 and 2017 and to describe the phenotype of patients. Methods: In this multicenter retrospective descriptive cohort study, we collected growth and pubertal parameters, associated comorbidities, treatment, and karyotype in patients diagnosed at age <18 years between 1993 and 2022. We assessed age-appropriate recommendation follow-up (children, adolescents and adults) according to the 2007 guidelines if the last visit was before 2017 (18 recommendations) and the 2017 guidelines if the last visit was after 2017 (19 recommendations). Results: We included 68 patients followed at Lausanne University Hospital (n=64) and at Neuchatel Regional Hospital (RHNe) (n=4). 2.9% of patients underwent all recommended investigations. Overall, 68.9 ± 22.5% and 78.5 ± 20.6% of the recommendations were followed, before and after 2017 respectively. High implementation rates were found for height, weight and BMI (100%), cardiac (80 to 100%) and renal (90 to 100%) imaging. Low implementation rates were found for Ear, Nose and Throat (ENT) (56.5%), skin (38.5%), dental (23.1%), ophthalmological (10%) and cholestasis (0 to 29%) assessments, depending on age and time of visit. In adults (n=33), the mean proportion of followed recommendations was lower before than after 2017: 63.5 ± 25.8% vs. 78.7 ± 23.4%, p=0.039. Conclusion: Growth parameters, cardiac and renal imaging are well followed. However, efforts should be made for dental, ENT, ophthalmological, skin and cholestasis assessments. Adequacy of follow-up improved with the quality of transition to adult care. [ABSTRACT FROM AUTHOR]

Drug safety monitoring is essential for developing efficient and safe treatments. It starts with preclinical toxicology studies and continues with the observation and analysis of potentially harmful effects in humans throughout the whole drug life cycle. Safety surveillance during the clinical phase is of paramount importance for protecting the health of clinical trial (CT) participants at a period when relatively little is known about the drug safety profile, and for reassuring that detected risks are minimized when the product obtains marketing approval. This review aimed to investigate current safety surveillance methods during drug development worldwide, in order to identify potential gaps and opportunities for amelioration. To this end, international guidelines, standards, and local legislations about CTs were reviewed and compared. Our review revealed common strategies, mainly in alignment with international guidelines, especially concerning the systematic collection, assessment, and expedition of adverse events by investigators and sponsors and the preparation of periodic aggregate safety reports by sponsors, as a means to inform health authorities (HAs) about the evolving benefit–risk balance of the investigational product. Inconsistencies in safety surveillance mainly concerned local expedited reporting requirements. Significant gaps were identified in the methodologies for aggregate analyses and the responsibilities of HAs. Addressing the regulatory discrepancies and harmonizing the safety surveillance processes at a global level would increase the usability of safety data accumulated by clinical studies worldwide, thus enabling and hopefully accelerating the development of safe and efficient drug therapies.

Background: Several pivotal studies and international guidelines on the perioperative management of rectal cancer have been published. However, little is known about the current state of perioperative management of rectal cancer patients in clinical practice worldwide. Methods: An online survey including 13 questions focusing on key topics related to the perioperative management of patients with rectal cancer was conducted among colorectal surgeons registered within the database of the Research Institute Against Digestive Cancer (IRCAD). Results: A total of 535 respondents from 89 countries participated in the survey. Most surgeons worked in the European region (40.9%). Two hundred and fifty-four respondents (47.5%) performed less than 25% of surgical procedures laparoscopically. The most commonly used definition of the upper limit of the rectum was a fixed distance from the anal verge (23.4%). Magnetic resonance imaging was used to define the upper limit of the rectum by 258 respondents (48.2%). During total mesorectal excision (TME), 301 respondents (56.3%) used a high-tie technique. The most commonly constructed anastomosis was an end-to-end anastomosis (68.2%) with the majority of surgeons performing a leak test intraoperatively (88.9%). A total of 355 respondents (66.4%) constructed a diverting ostomy, and the majority of these surgeons constructed an enterostomy (82%). A total of 208 respondents (39.3%) closed a stoma within 8 weeks. Lastly, 135 respondents (25.2%) introduced a solid diet on postoperative day 1. Conclusion: There is considerable heterogeneity in the perioperative management of rectal cancer patients worldwide with several discrepancies between current international practice and recommendations from international guidelines. To achieve worldwide standardization in rectal cancer care, further research is needed to elucidate the cause of this heterogeneity and find ways of improved implementation of best practice recommendations.

Abstract The use of instrumental tools for improving both the diagnostic accuracy and the prognostic soundness in patients with disorders of consciousness (DOC) plays an important role. However, the most recent international guidelines on DOC published by the American and the European Academies of Neurology and by the UK Royal College of Physicians contain heterogeneous recommendations on the implementation of these techniques in the clinical routine for both diagnosis and prognosis. With the present work, starting from the comparison of the DOC guidelines’ recommendations, we look for possible explanations behind such discrepancies considering the adopted methodologies and the reference health systems that could have affected the guidelines’ perspectives. We made a provocative argument about the need to find the most appropriate common methodology to retrieve and grade the evidence, increase the meta-analytic studies, and reduce the health policies that influence on the guidelines development that, in turn, should inform the health policies with the strongest scientific evidence.

Scabies infestation is a growing public health issue due to its world wide increase of incidence. The objective of this study was to proof treatment resistance towards treatment, which was applied according to international guidelines. This is a controversial issue since treatment failures were believed to be due to false application oft he treatment. Here, we proof fort he first time this treatment resistance by videomicroscopic evaluation. Additionally an escalation therapy is described, which led to an effective treatment.

The necessity to create stable and transparent economic conditions has made combating money laundering a universal policy on the agenda of parliaments and governments by all countries. This is currently the specific issue of the Iran monetary and banking system. In this regard, the infrastructural approach includes all effective dimensions of international anti-money laundering mechanisms such as Basel Committee indices and recommendations of the Financial Action Task Force, and the experiences of other countries show that applying factors of this approach can enhance Iran monetary and banking system internationally and decreases money laundering risk. In order to identify the challenges in this area and reach a model which includes a set of infrastructural factors in fighting money laundering, this study uses qualitative and quantitative parts; in qualitative part, the criteria raised by experts through face-to-face interviews and multi-stage coding, content analysis, and Fuzzy Delphi method, and in quantitative part, the criteria raised by questionnaire and factor analysis technique, and the RMSEA index have been used for fitting the model. Based on international guidelines, the proposed infrastructural model consists of functional, contextual, and structural dimensions and findings indicate that a systematic application of the proposed model improves the efficiency of anti-money laundering system and helps optimal management of anti-money laundering challenges of banks. In this regard, the relative weights of legal, political, geopolitical, and risk-taking components of the structural dimension highlight the importance and necessity of focusing on this dimension and its components of the Iran banking system.

Both the European Society of Cardiology (ESC) and the American College of Cardiology (ACC/AHA) have recently released guidelines on the management of patients with secondary mitral regurgitation. This includes defining, classifying, and assessing the severity of secondary mitral regurgitation. These guidelines are also the first to incorporate the use of transcatheter edge-to-edge repair in decision-making based on recent studies. The review highlights the strengths and shortcomings of these studies and the applicability and generalisability of these results to assist in decision-making for the heart time. It also emphasises the importance of shared decision-making via the heart team. Echocardiography plays an important role in the assessment of these patients although these may be specifically for primary mitral insufficiency. The optimal guideline-directed medical therapy should be the first line of treatment followed by mechanical intervention. The choice of intervention is best directed by a specialist multidisciplinary team. Concomitant revascularization should be performed in a subgroup of patients with severe secondary mitral regurgitation given the role of adverse LV remodelling in propagation of the dynamic secondary MR. The guidelines need further confirmation from high-quality studies in the near future to decision-making towards either TEER, mitral valve replacement, or mitral valve repair with or without a subvalvular procedure.

Introduction: To assess the current approaches and perioperative treatments of laparoscopic right hemicolectomy (LRHC) and to highlight similarities and differences with international guidelines and scientific evidence, we conducted a survey for surgeons across the globe. Methods: All digestive and colorectal surgeons registered with the database of the Research Institute against Digestive Cancer (IRCAD) were invited to take part in the survey via email and through the social media networks of IRCAD. Results: There were a total of 440 respondents from 78 countries. Most surgeons worked in the European region (38.6%) followed by the Americas (34.1%), the Eastern Mediterranean region (13.0%), the South-East Asian region (5.9%), the Western Pacific region (4.8%), and Africa (3.2%) respectively. Over half of the respondents performed less than 25% of right hemicolectomies laparoscopically where 4 ports are usually used by 68% of the surgeons. The medial-to-lateral, vessel-first approach is the approach most commonly used (74.1%). The most common extraction site was through a midline incision (53%) and an abdominal drain tube is routinely used by 52% of the surgeons after surgery. A total of 68.6% of the responding surgeons perform the majority of the anastomoses extracorporeally. Finally, we found that the majority of responders (60.7%) routinely used mechanical bowel preparations prior to LRHC. Conclusion: Regarding several topics related to LRHC care, a discrepancy was observed between the current medical practice and the recommendations from RCTs and international guidelines and significant regional differences were observed.

The practice of the regionalization principle in Article 6 Sanitary and Phytosanitary (SPS) Agreement is still conflicted. This is because of several cases regarding the members misinterpretation of international guidelines in the regionalization principle, such as India – Agricultural Products and Russia – Pigs (EU). Recently, Coronavirus Diseases 2019 (Covid-19) has been considered to affect animal trade. Such conditions prompt the World Trade Organization (WTO) to recommend the Members to take SPS Measures to protect their domestic market. However, the trade would be inhibited in case the country-wide ban approach is applied. Therefore, this paper discusses the possible SPS measures under the regionalization principle to promote the trade during the pandemic according to WTO decisions from previous cases in line with the VCLT of 1969. The research result shows that the Covid-19 is an obstacle to international trade and makes humans and animals vulnerable to this virus. Consequently, many animal trades have been banned to prevent its spread. To deal with this condition, Indonesia could apply the regionalization principle in Article 6 SPS Agreement. Moreover, the government should update the quarantine law by pointing out the regionalization principle, unlike the zone system rules only applied to animals susceptible to Food Mouth Disease

This study aims to determine the extent in which the 2019 Global Initiative for Asthma (GINA) guidelines were being met.Methods: A retrospective study of patients with asthma exacerbations admitted to the University of Malaya Medical Centre (UMMC) and Pantai Hospital Kuala Lumpur (PHKL), Malaysia from 1 July 2019 to 31 December 2019.Results: There were significant numbers of patients with previous admissions for asthma in both centres, with almost 50% experiencing an exacerbation in the previous year. Approximately 75% of the patients considered their asthma to be controlled when asked, despite many of them having had a history of acute exacerbations in the previous year. When cross-checked, the level of GINA-defined asthma control remained low, with only 6.4% of the patients deemed to have good control, while asthma was partially controlled in 25.6% of the patients and uncontrolled in 68% of the patients. About 72.1% of the patients reported daytime symptoms, 65.1% of the patients reported night-time symptoms, 70.9% of the patients required frequent usage of rescue inhalers and 72.1% of the patients reported some limitation in their activity prior to the current asthma exacerbation. Almost a quarter of the patients who were admitted had severe or life-threatening exacerbations as defined by GINA. These patients had more hospitalizations in a year and were more likely to have previous admissions requiring non-invasive and invasive ventilation. They were also more likely to be on GINA Step 5 treatment, had a lower mean percent predicted FEV1 and a higher baseline blood eosinophil count. Multivariate analysis revealed that baseline eosinophil count were independently associated with severe or life-threatening asthma exacerbations (odds ratio: 1.01, 95% confidence interval: 1.00– 1.01, p=0.001). Failure to adhere to daily controller medications was high in this study (37.2%).Conclusion: Although the management of asthma exacerbations in tertiary hospitals in Southeast Asia is largely congruous with international guidelines, there is room for improvement. As there is a marked discrepancy between patient-perceived and guideline-defined asthma control, efforts to increase awareness on the dangers of uncontrolled asthma are warranted.Keywords: acute care, Southeast Asia, severe asthma, international guidelines, management

This article argues that the centrality of the statistical standards for developing the global and national statistical system is explained by the normative work of the Statistical Commission of the United Nations, being the highest decision-making body of the global statistical system. It further presents the centrality of the statistical standard in the terms of reference that guides the normative work of the Statistical Commission. While what constitutes a statistical standard is not formally defined by the Statistical Commission, the article continues in introducing stylized facts for statistical standards based on the practices of developing and adopting normative standards by the Statistical Commission. These stylized facts bring into focus the categories of statistical standards and the consultative cycle for the development and adoption of these standards. [ABSTRACT FROM AUTHOR]

Objectives: Current international guidelines recommend tocolytic treatment by at least 48 h to complete fetal lung maturation and to ensure in-utero transfer to a perinatal center before 34 weeks of gestation in patients with threatened preterm birth. According to the results of former surveys, significant differences between daily clinical practice patterns and evidence-based guideline recommendations regarding tocolytic treatment have been demonstrated. We compared data from a nation-wide survey on the practice of initial tocolysis with recommendations from the current German Guideline 015/025 "Prevention and Treatment of Preterm Birth".Study Design: 632 obstetric units in Germany received a link to an online questionnaire between January 20th and March 31st 2020, which was developed according to national and international recommendations and guidelines. Collected data was descriptively analyzed by performing measures of frequency.Results: The response rate was 19%; 51 (42.5%) of the respondents consider CTG tracing with ≥ 4 contractions within 20 min, 49 (40.8%) cervical length measurement of ≤ 25 mm and 13 (10.9%) subjective contractions as the most significant decision-making criteria for tocolysis; 47 (39.2%) of obstetric units initiate tocolysis earliest at 23 + 0, 34 (28.3%) at 22 + 0, 26 (21.7%) at 23 + 5 and 13 (10.8%) at 24 + 0 weeks of gestation; 104 (86.7%) stop tocolysis latest at the 34 + 0 weeks of gestation, 42 (35.0%) obstetric units administer antenatal corticosteroids at 23 + 5, 16 (13.3%) at 22 + 0, and 13 (10.8%) at 24 + 0 weeks of gestation. Calcium channel blockers are the first-line tocolytic drug used by 59 (49.1%) of the obstetric units, followed by intravenous betamimetics as bolus (n = 26, 21.7%) and atosiban (n = 20, 16.7%). Severe side-effects were observed by 105 (70%) of the respondents in association with the use of betamimetics, 14 (9.3%) with the use of nifedipine and 30 (20.0%) with nitroglycerine patches. The German guideline was considered the most important decision-making support by 78 (65%) of the obstetric units, followed by hospital specific SOPs/algorithms (n = 31, 25.8%).Conclusion: Our survey highlights a considerable discrepancy between evidence-based guideline recommendations and daily clinical practice.

Introduction:Hypertension in children has increased globally over the past 20 years; yet, little is known about this issue among disadvantaged communities from low- and middle-income countries. Age-, sex-, and height-adjusted normative tables are the “gold” standard for the diagnosis and estimation of pediatric hypertension worldwide, but it is unclear whether the use of international standards is appropriate for all contexts. The purpose of this study was to evaluate and compare different international references to identify hypertension among South African school-aged children from disadvantaged communities.MethodsBlood pressure, weight, and height were measured in a cohort of 897 children aged 8–16 years from eight peri-urban schools in the Eastern Cape of South Africa. Cross-sectional prevalence of hypertension was calculated according to American, German, and global normative tables, as well as pseudo-normative data from the own study population. Isolated systolic hypertension and body mass index (BMI) were considered markers for cardiovascular disease. Multinomial logistic regression was used to compare the likelihood of blood pressure categorization with increasing BMI levels.ResultsHypertension prevalence ranged from 11.4% with the pseudo-normative study tables to 28.8% based on the German reference. Global guidelines showed the highest agreement both among international standards (92.5% with American guidelines) and with the study reference (72.5%). While the global and the American references presented higher systolic over diastolic hypertension rates (23.6 vs. 10.6% and 24.2 vs. 14.7%, respectively), the American guidelines predicted the highest increased risk for hypertension stage 2 [odds ratio, 1.72 (95% confidence interval: 1.43–2.07)] with raising levels of BMI.ConclusionOur results support the heterogeneity of blood pressure estimates found in the South African literature, and highlight the underrepresentation of African children in international guidelines. We call for caution in the use of international standards in different contexts and advocate for the development of normative tables that are representative of the South African pediatric population necessary to ensure an accurate identification of hypertension both from the clinical and epidemiological perspective.

Background: Long-standing ulcerative colitis has been associated with an increased risk of colorectal cancer (CRC). Current guidelines recommend endoscopic CRC screening after 8 years of disease duration. The objectives of our study were to assess the adherence to recommendations and the quality of endoscopic procedure in long-standing ulcerative colitis. Methods: This is a retrospective cohort study. We selected patients included in the Swiss IBD cohort with a disease duration of ≥8 years and an extension above the rectosigmoid junction. The complementary medical chart review focused on endoscopy and associated histological reports in 8 Swiss centers. Descriptive analyses focused on patients and their colonoscopies. Results: 309 colonoscopies were conducted among 116 patients with the following characteristics: women 47%, mean age at diagnosis 31 years, and pancolitis disease extent in 65.5% of cases; 38.8% of patients had a first screening colonoscopy 10 years. Cecal intubation was performed in 94.5% of cases, and bowel preparation was good to excellent in 61.5% of endoscopies. Chromoendoscopy was used in 7.4% of cases, and the mean withdrawal time was 16.4 min. Dysplasia was found in 6.2% of cases. Conclusion: Despite current international recommendations, a significant number of patients did not receive a proper endoscopic surveillance. An increased use of chromoendoscopy, monitoring of withdrawal time, and appropriate bowel preparation would increase the quality of CRC screening. The adherence to screening guidelines and endoscopic quality should be promoted and standardized.

The objective: to provide pathogenetic justification for the need for extracorporeal blood purification in the new coronavirus infection.Results: the article analyzes guidelines and the first experience of using extracorporeal methods in the new coronavirus infection in different countries. It has been demonstrated that methods of extracorporeal blood purification have complex pleiotropic (multiple) effects and can quickly normalize the level of cytokines and other pathogenic factors, thereby preventing/reducing the severity of organ disorders. The article specifies the criteria for choosing an extracorporeal method, as well as indications for its early and late use.

Abstract Background Neurosurgical resection represents an important treatment option in the modern, multimodal therapy approach of brain metastases (BM). Guidelines for perioperative imaging exist for primary brain tumors to guide postsurgical treatment. Optimal perioperative imaging of BM patients is so far a matter of debate as no structured guidelines exist. Methods A comprehensive questionnaire about perioperative imaging was designed by the European Association of Neuro-Oncology (EANO) Youngsters Committee. The survey was distributed to physicians via the EANO network to perform a descriptive overview on the current habits and their variability on perioperative imaging. Chi square test was used for dichotomous variables. Results One hundred twenty physicians worldwide responded to the survey. MRI was the preferred preoperative imaging method (93.3%). Overall 106/120 (88.3%) physicians performed postsurgical imaging routinely including MRI alone (62/120 [51.7%]), postoperative CT (29/120 [24.2%]) and MRI + CT (15/120 [12.5%]). No correlation of postsurgical MRI utilization in academic vs. non-academic hospitals (58/89 [65.2%] vs. 19/31 [61.3%], p = 0.698) was found. Early postoperative MRI within ≤72 h after resection is obtained by 60.8% of the participants. The most frequent reason for postsurgical imaging was to evaluate the extent of tumor resection (73/120 [60.8%]). In case of residual tumor, 32/120 (26.7%) participants indicated to adjust radiotherapy, 34/120 (28.3%) to consider re-surgery to achieve complete resection and 8/120 (6.7%) to evaluate both. Conclusions MRI was the preferred imaging method in the preoperative setting. In the postoperative course, imaging modalities and timing showed high variability. International guidelines for perioperative imaging with special focus on postoperative MRI to assess residual tumor are warranted to optimize standardized management and adjuvant treatment decisions for BM patients.

The presented review highlights current understandings of prophylaxis for infective endocarditis (IE). The historic aspects of the concept development of antibacterial prophylaxis (ABP) for IE, the main approaches and the rationale for changing the principles of ABP in recent years are described. There are detailed clarifications of published international and national recommendations, in particular, of European Society of Cardiology, National Institute for Health and Clinical Excellence, American Heart Association/American College of Cardiology and Japanese Circulation Society. The critical estimation of earlier adopted international guidelines with analysis of influence of partial or absolute ABP restrictions on the incidence of IE and its complications including fatality rate are presented.

Obstructed defecation syndrome (ODS) is a form of constipation that influences the quality of life in most patients and is an important health care issue. In 2004 Longo introduced a minimal invasive trans-anal approach known as Stapled Trans-Anal Rectal Resection (STARR) in order to correct mechanical disorders such as rectocele or rectal intussusception, two conditions present in more than 90% of patients with ODS. Considering the lack of a common view around ODS and STARR procedure. the aim of our study is to review the literature about preoperative assessment, operative features and outcomes of the STARR technique for the treatment of ODS. We performed a systematic search of literature, between January 2008 and December 2020 and 24 studies were included in this review. The total number of patients treated with STARR procedure was 4,464. In conclusion STARR surgical procedure has been proven to be safe and effective in treating symptoms of ODS and improving patients Quality of Life (QoL) and should be taken in consideration in the context of a holistic and multi modal approach to this complex condition. International guidelines are needed in order to optimize the diagnostic and therapeutic process and to improve outcomes.

Background: Acute pyelonephritis (AP) is a common bacterial infection in childhood. Follow-up guidelines on these children are controversial. This study aimed to identify risk factors for kidney scarring and vesicoureteral reflux (VUR). Furthermore, international follow-up guidelines were used for simulation to evaluate sensitivity and specificity. Methods: Urinary culture-confirmed first-time AP patients (aged 0–14 years) were enrolled (n = 421) from review of patient charts. All underwent kidney ultrasound (US) and a technetium-99m-dimercaptosuccinic acid (DMSA) scan or technetium-99m-mercaptoacetyltriglycine scinti-renography (MAG3) at 4–6 months of follow-up. The international guidelines used for simulation were from the National Institute of Health UK (NICE), the American Association of Paediatrics (AAP) and the Swedish Paediatric Society (SPS). Results: 17.8% presented with an abnormal DMSA/MAG3 at follow-up, 7.1% were diagnosed with VUR grades III–V and 4.7% were admitted for surgery. Non-Escherichia coli infections, abnormal kidney US, elevated creatinine and delayed response to treatment (>48 h) were risk factors for abnormal DMSA findings and VUR grades III–V. NICE and SPS guidelines showed best sensitivity in diagnosing VUR grades III–V (75%) compared with AAP (56%). Conclusions: Risk factors are helpful in identifying the children in need of further investigations and minimizing invasive work-up for the rest. International guidelines on follow-up detect a varying number of children with kidney damage and/or significant VUR. Future work must focus on identifying more specific risk factors, better imaging, or specific biomarkers, to enhance sensitivity and specificity in detecting the children at high risk for developing recurrent infections and/or nephropathy.

Abstract Background The indicating FTA card is a dry medium used for collection of cervical samples. HPVIR is a multiplex real-time PCR test that detects 12 high-risk human papillomavirus types (hrHPV) and provides single genotype information for HPV16, − 31, − 35, − 39, − 51, − 56, and − 59 and pooled type information for HPV18/45 and HPV33/52/58. The aim of this study was to evaluate whether a strategy with cervical samples collected on the FTA card and subsequently analysed with the HPVIR test complies with the criteria of the international guidelines for a clinically validated method for cervical screening. Methods We performed a non-inferiority test comparing the clinical sensitivity and specificity of the candidate test (FTA card and HPVIR) with a clinically validated reference test (Cobas® HPV test) based on liquid-based cytology (LBC) samples. Two clinical samples (LBC and FTA) were collected from 896 participants in population-based screening. For evaluation of the specificity we used 799 women without ≥ CIN2, and for clinical sensitivity we used 67 women with histologically confirmed ≥ CIN2. The reproducibility was studied by performing inter- and intra-laboratory tests of 558 additional clinical samples. Results The clinical sensitivity and specificity for samples collected on the FTA card and analysed using the HPVIR test were non-inferior to samples analysed with the Cobas® HPV test based on LBC samples (non-inferiority test score, p = 1.0 × 10− 2 and p = 1.89 × 10− 9, respectively). Adequate agreement of > 87% was seen in both the intra- and inter-laboratory comparisons. Conclusions Samples collected on the indicating FTA card and analysed with HPVIR test fulfil the requirements of the international guidelines and can therefore be used in primary cervical cancer screening.

Unparalleled changes in technology such as remote sensing, mobile devices (e.g. tablets, smartphones), Web questionnaires, online dissemination of results (e.g. infographics, social media) as well as electronic data archiving and anonymization of micro-data, are increasingly transforming the way countries conduct agricultural censuses and sample surveys. Their use facilitate both data collection and data dissemination by enhancing reliability, timeliness, readability and comprehensibility of census results. This is discussed in Volume 2 of the new FAO guidelines on the World Programme for Census of Agriculture 2020 (WCA 2020) and summarized in this paper.

Due to the rapid and unrestrained growth of urbanization worldwide since the second half of the twentieth century, the global community is confronted with a broad spectrum of challenges. In response, the request for more sustainable cities developed in recent decades. Urban agenda setting, like the foundation of the UN-Habitat, emerged subsequently in the public policy process to countervail the negative impacts of the progress, especially in developing countries. The article wants to provide the reader with a brief introduction to global urban agendas in general and the New Urban Agenda (NUA) in specific, especially how they approach urban challenges. The analysis offers an overview of the context of the implementation of urban agendas and definitions of sustainability in its setting. Furthermore, it is examined, how non-binding doctrinaire documents like the NUA should be implemented on the regional and national levels. The challenges in implementing these urban agendas, the definition of sustainable urban agendas, and common international challenges are deconstructed and compared with the guiding principles of the NUA. The research question highlights potential approaches, how to improve the implementation of these agendas, and contributes to reducing the research gap of the global south in this regard. Therefore, as a case study, a closer look at the exemplary situation of the developing country Brazil, the local urban evolution, planning policies, and the local challenges are undertaken. To conclude, the challenges of the new urban era identified will be briefly reflected and possible pathways through alternative mechanisms, recommended by the NUA and other international guidelines, pointed out to foster implementation to the detriment of traditional local hard policy mechanisms.

The review is devoted to the practical aspects of infective endocarditis (IE) prevention, the issues of which, as before, remain the subject of lengthy discussions. Despite repeatedly updated national and international guidelines on this topic, medical practitioners are not always fully aware of antibiotic prophylaxis of IE. After a brief consideration of the etiological, pathogenetic features and risk factors of the disease, the main provisions of 2015 European Society of Cardiology guidelines on IE prevention, which were approved by the Russian Society of Cardiology, are presented. The categories of patients with the highest risk of IE, procedures associated with an increased risk of IE (dental and other invasive procedures) are described in detail. The main practical approaches to the identification of risk groups and performing invasive procedures that influence the decision to prescribe antibiotic prophylaxis are described. Particular attention is paid to the characteristics of both first-line antibiotic drugs and alternative agents for penicillin allergy or in cases of β-lactamase secreting pathogens.

Studies conducted on the chemical composition of Zamzam water are conflicting especially for arsenic. Therefore, the aim of our study is to study the composition of tap and bottled Zamzam water and to compare its quality according to international guidelines of drinking water. Six Zamzam tap water samples as well as one bottled sample were analyzed according to standard methods (APHA) for their chemical constituents (pH, TDS, Na, K, Mg, Ca, Fe, Cu, Zn, Cd, Pb, Mn, Al, As, Cl−, SO4−2, HCO3- and PO4−3). The results were compared to guidelines of WHO and EPA for quality of drinking water. All analyzed parameters were below the maximum allowable limits (MAL) of WHO and EPA (p˃0.05), with the exception of TDS. The average values of TDS (814 mg L−1 in tap zamzam water samples and 812 mg L−1 in bottled sample) were below the MAL of WHO (1000 mg L−1) but exceeded the limit that defined by EPA as a non-enforceable guidelines (500 mg L−1) (p˂0.05). Compared to the collected tap zamzam water samples, bottled sample had significantly lower levels of Na, PO4−3 (p˂0.05) and Cu (p˂0.01). The study concluded that Zamzam water has acceptable chemical composition including arsenic, except for TDS that exceeds the high non-enforceable accepted limit according to EPA.

Both the European Society of Cardiology (ESC) and the American College of Cardiology (ACC/AHA) have recently released guidelines on the management of patients with secondary mitral regurgitation. This includes defining, classifying, and assessing the severity of secondary mitral regurgitation. These guidelines are also the first to incorporate the use of transcatheter edge-to-edge repair in decision-making based on recent studies. The review highlights the strengths and shortcomings of these studies and the applicability and generalisability of these results to assist in decision-making for the heart time. It also emphasises the importance of shared decision-making via the heart team. Echocardiography plays an important role in the assessment of these patients although these may be specifically for primary mitral insufficiency. The optimal guideline-directed medical therapy should be the first line of treatment followed by mechanical intervention. The choice of intervention is best directed by a specialist multidisciplinary team. Concomitant revascularization should be performed in a subgroup of patients with severe secondary mitral regurgitation given the role of adverse LV remodelling in propagation of the dynamic secondary MR. The guidelines need further confirmation from high-quality studies in the near future to decision-making towards either TEER, mitral valve replacement, or mitral valve repair with or without a subvalvular procedure.
