Pancreaticopleural fistula as the inaugural presentation of chronic pancreatitis: A case report.

INTRODUCTION: Pancreaticopleural fistula is a rare complication most associated with alcohol-induced chronic pancreatitis. This usually presents with chest symptoms instead of abdominal ones. Diagnosis requires a high index of suspicion in patients with pancreatitis and persistent pleural effusions. PRESENTATION OF CASE: We present a case of an 81-years-old man admitted in the emergency department with a one week complaints of productive cough, fever, dyspnea and left-side chest pain. The chest X-ray revealed a moderated-volume left-side pleural effusion. The pleural fluid analysis was consistent with an exsudative pleural effusion with high levels of amylase. The thoracoabdominal CT raised the suspicion of a pancreaticopleural fistula, confirmed by ERCP. A pancreatic main duct stenting was performed with good results. The patient was discharged asymptomatic after 18 days of hospitalization. DISCUSSION: Because of PPF insidious presentation it poses a great number of differential diagnosis, so pleural fluid analysis is of paramount importance with high levels of amylase confirming the diagnosis. MRCP and ERCP may establish the fistulous tract between the pancreatic duct and the pleural cavity, with the latter being also therapeutic. CONCLUSION: The rarity of this complication related to pancreatitis and the seldomly presence of abdominal pain in contrast with chest symptoms poses a diagnostic challenge.

Unusual presentation of pancreatitis: Inguinoscrotal edema mimicking an incarcerated hernia - a case report.

INTRODUCTION: In rare instances, pancreatitis can manifest as inguinal edema without typical abdominal symptoms, posing diagnostic challenges. CASE PRESENTATION: We report a case of a man in his 40s, with alcohol addiction, who presented with left inguinal pain and swelling but no other abdominal complaints. Physical examination revealed inguinal tenderness and edema, with no hernia signs. Laboratory results showed leukocytosis and elevated C-reactive protein, inconsistent with the patient's symptoms. Abdominopelvic CT scan revealed peripancreatic fat densification and retroperitoneal fluid extending into the inguinal area. No hernia was evident. Extended analysis revealed elevated amylase and lipase levels, sustaining the diagnosis of pancreatitis. The patient responded well to supportive care and was discharged symptom-free. DISCUSSION: Acute pancreatitis emerging as an inguinoscrotal swelling, in the absence of any abdominal symptoms or signs, is extremely rare and can mimic more common causes of inguinoscrotal swellings, such as incarcerated hernias. This case highlights the ability of leaking pancreatic juice to track widely in the retroperitoneal tissues, particularly on the left side. A high level of suspicion, in combination with a CT scan, is essential for achieving an accurate diagnosis and determining the disease's extent. Failure to diagnose correctly could lead to unnecessary surgical procedures and inappropriate/delayed medical care. CONCLUSION: Inguinal edema as the sole presentation of acute pancreatitis is extremely rare. Therefore, it is essential to maintain a high index of suspicion, especially in patients with a history of alcohol consumption, in order to proceed with prompt treatment and avoid unnecessary surgery.

Proteomics Reveals mRNA Regulation and the Action of Annexins in Thyroid Cancer.

Differentiated thyroid cancer is the most common malignancy of the endocrine system. Although most thyroid nodules are benign, given the high incidence of thyroid nodules in the population, it is important to understand the differences between benign and malignant thyroid cancer and the molecular alterations associated with malignancy to improve detection and signal potential diagnostic, prognostic, and therapeutic targets. Proteomics analysis of benign and malignant human thyroid tissue largely revealed changes indicating modifications in RNA regulation, a common cancer characteristic. In addition, changes in the immune system and cell membrane/endocytic processes were also suggested to be involved. Annexin A1 was considered a potential malignancy biomarker and, similarly to other annexins, it was found to increase in the malignant group. Furthermore, a bioinformatics approach points to the transcription factor Sp1 as being potentially involved in most of the alterations seen in the malignant thyroid nodules.

Biomarkers of hypoxic-ischemic encephalopathy: a systematic review.

BACKGROUND: Current diagnostic criteria for hypoxic-ischemic encephalopathy in the early hours lack objective measurement tools. Therefore, this systematic review aims to identify putative molecules that can be used in diagnosis in daily clinical practice (PROSPERO ID: CRD42021272610). DATA SOURCES: Searches were performed in PubMed, Web of Science, and Science Direct databases until November 2020. English original papers analyzing samples from newborns > 36 weeks that met at least two American College of Obstetricians and Gynecologists diagnostic criteria and/or imaging evidence of cerebral damage were included. Bias was assessed by the Newcastle-Ottawa Scale. The search and data extraction were verified by two authors separately. RESULTS: From 373 papers, 30 met the inclusion criteria. Data from samples collected in the first 72 hours were extracted, and increased serum levels of neuron-specific enolase and S100-calcium-binding protein-B were associated with a worse prognosis in newborns that suffered an episode of perinatal asphyxia. In addition, the levels of glial fibrillary acidic protein, ubiquitin carboxyl terminal hydrolase isozyme-L1, glutamic pyruvic transaminase-2, lactate, and glucose were elevated in newborns diagnosed with hypoxic-ischemic encephalopathy. Moreover, pathway analysis revealed insulin-like growth factor signaling and alanine, aspartate and glutamate metabolism to be involved in the early molecular response to insult. CONCLUSIONS: Neuron-specific enolase and S100-calcium-binding protein-B are potential biomarkers, since they are correlated with an unfavorable outcome of hypoxic-ischemic encephalopathy newborns. However, more studies are required to determine the sensitivity and specificity of this approach to be validated for clinical practice.

Management of infantile hemangiomas-experience of a tertiary hospital.

The purpose of the study is to describe the experience of a multidisciplinary team in a tertiary hospital regarding the management of Infantile Hemangiomas (IH). The method employed is a retrospective analysis of patients with IH followed in a tertiary pediatric hospital between January 2010 and May 2022. A total of 393 IH were diagnosed (56.7% female), with a median age of 5 months (interquartile range (IQR), 3-10). Imaging investigation was necessary for diagnosis and for exclusion of other IH in 9.2% and 14.3%, respectively. Focal (74.0%) and superficial (59.7%) lesions were more frequent as was facial location (35.9%). Pre-treatment ulceration or hemorrhage occurred in 6.6%. At follow-up, 87.4% regressed partially and 12.6% completely; 2.7% relapsed. Propranolol was started in 30.0% of cases for a median period of 9 months (IQR, 6-12), mainly due to esthetic concerns (41.9%). Side effects occurred in 8.3% (sleep disturbance in 5.1%). Only 1.7% were refractory and 5.9% had a rebound effect. Eleven patients were treated with topical timolol and 41 underwent surgery. Patients that were treated with propranolol had more risk factors (p = 0.016) and presented deeper lesions (p < 0.001) with a larger diameter (p < 0.001); total IH regression was less frequent (p < 0.001). Since 2020, twice-daily dosage was more frequently prescribed than three times daily (p = 0.007) and inpatient initiation of propranolol decreased (p = 0.750), without significant difference in the incidence of adverse reactions, duration of treatment, and lesion evolution.  Conclusions: Our protocol proved to be safe and feasible in an outpatient setting and twice daily administration of propranolol was effective. The majority of IH showed at least partial regression. Early detection of high-risk IH is paramount and a multidisciplinary assessment by a specialized team is essential for adequate management. What is Known: • IH are the most common vascular tumors in childhood. Although the majority evolves favorably, treatment may be warranted in selected cases. • Early detection of high-risk IH is paramount, and a multidisciplinary assessment by a specialized team is essential for adequate management. What is New: • One-third of our sample was treated with propranolol. These patients had more risk factors and presented deeper lesions with a larger diameter, and tumor total regression was less frequent. • Our results reinforce safety and feasibility of propranolol initiation in an outpatient setting, including twice daily dosage.

[Lead Exposure as Cause of a Clinical Scenario of Cardiac Arrhythmias]. / A Exposição ao Chumbo na Base de um Quadro de Arritmias Cardíacas.

The recycling of used batteries has raised public health concerns as this activity is associated with occupational and environmental exposure to lead. We describe the case of a 26-year-old woman who experienced palpitations associated with headaches, fatigue and insomnia. Blood tests showed anemia (Hb 11.9 g/dL) and a lead concentration of 59 µg/dL. This was reported about four months after starting work in a battery recycling company. She left the company and, reported a gradual decrease in symptoms about one month later. The analytical study revealed a normalization of hemoglobin levels (12.2 g/dL) and a decrease in blood lead levels to 23.4 µg/dL. The health effects of lead exposure are nonspecific, and its diagnosis requires a high degree of suspicion. In this context, the collaboration between the Attending Physician and the Health and Safety Departments of companies is important.

A reciclagem de baterias usadas tem suscitado preocupações de saúde pública uma vez que esta atividade está associada à exposição ocupacional e ambiental ao chumbo. Descreve-se o caso de uma mulher de 26 anos que iniciou quadro de palpitações associado a cefaleias, fadiga e insónias, cerca de quatro meses após iniciar funções numa empresa de reciclagem de baterias. Analiticamente, observou-se anemia (Hb 11,9 g/dL) e plumbémia de 59 µg/dL. Cessou funções na empresa e, após um mês, referiu uma diminuição progressiva da sintomatologia. O estudo analítico revelou uma normalização dos valores da hemoglobina (12,2 g/dL) e uma diminuição do valor de chumbo no sangue para 23,4 µg/dL. Os efeitos na saúde da exposição ao chumbo são inespecíficos e o seu diagnóstico requer um alto grau de suspeição. Neste âmbito revela-se importante a articulação entre o médico assistente e os serviços de Saúde, Higiene e Segurança no Trabalho das empresas.

Enrichment of hepatic glycogen and plasma glucose from H218 O informs gluconeogenic and indirect pathway fluxes in naturally feeding mice.

Deuterated water (2 H2 O) is a widely used tracer of carbohydrate biosynthesis in both preclinical and clinical settings, but the significant kinetic isotope effects (KIE) of 2 H can distort metabolic information and mediate toxicity. 18 O-water (H2 18 O) has no significant KIE and is incorporated into specific carbohydrate oxygens via well-defined mechanisms, but to date it has not been evaluated in any animal model. Mice were given H2 18 O during overnight feeding and 18 O-enrichments of liver glycogen, triglyceride glycerol (TG), and blood glucose were quantified by 13 C NMR and mass spectrometry (MS). Enrichment of oxygens 5 and 6 relative to body water informed indirect pathway contributions from the Krebs cycle and triose phosphate sources. Compared with mice fed normal chow (NC), mice whose NC was supplemented with a fructose/glucose mix (i.e., a high sugar [HS] diet) had significantly higher indirect pathway contributions from triose phosphate sources, consistent with fructose glycogenesis. Blood glucose and liver TG 18 O-enrichments were quantified by MS. Blood glucose 18 O-enrichment was significantly higher for HS versus NC mice and was consistent with gluconeogenic fructose metabolism. TG 18 O-enrichment was extensive for both NC and HS mice, indicating a high turnover of liver triglyceride, independent of diet. Thus H2 18 O informs hepatic carbohydrate biosynthesis in similar detail to 2 H2 O but without KIE-associated risks.

Peptidomics Unveils Distinct Acetylation Patterns of Histone and Annexin A1 in Differentiated Thyroid Cancer.

Thyroid cancer is a common malignancy of the endocrine system. Nodules are routinely evaluated for malignancy risk by fine needle aspiration biopsy (FNAB), and in cases such as follicular lesions, differential diagnosis between benign and malignant nodules is highly uncertain. Therefore, the discovery of new biomarkers for this disease could be helpful in improving diagnostic accuracy. Thyroid nodule biopsies were subjected to a precipitation step with both the insoluble and supernatant fractions subjected to proteome and peptidome profiling. Proteomic analysis identified annexin A1 as a potential biomarker of thyroid cancer malignancy, with its levels increased in malignant samples. Also upregulated were the acetylated peptides of annexin A1, revealed by the peptidome analysis of the supernatant fraction. In addition, supernatant peptidomic analysis revealed a number of acetylated histone peptides that were significantly elevated in the malignant group, suggesting higher gene transcription activity in malignant tissue. Two of these peptides were found to be robust malignancy predictors, with an area under the receiver operating a characteristic curve (ROC AUC) above 0.95. Thus, this combination of proteomics and peptidomics analyses improved the detection of malignant lesions and also provided new evidence linking thyroid cancer development to heightened transcription activity. This study demonstrates the importance of peptidomic profiling in complementing traditional proteomics approaches.

Migrant and ethnic minority nurses' experience of working in European health services: a qualitative study.

OBJECTIVE: To analyze the perception of culture and experience of working in European health services of a purposive sample of qualified migrant and ethnic minority nurses currently living in Belgium, Portugal, Spain and Turkey. METHOD: A qualitative phenomenological method was chosen. Individual interviews took place with 8 qualified migrant and ethnic minority nurses currently living in four European countries. Thematic analysis was conducted using Braun and Clark's stages after qualitative data had been verbatim transcribed, translated into English, and analyzed. RESULTS: Four themes and 4 subthemes emerged from thematic analysis of the transcripts. CONCLUSION: Migrant and ethnic minority nurses working in the European Union experience and witness discrimination and prejudice from patients and colleagues due to cultural differences. European health services should closely monitor and address discrimination and prejudice towards migrant and ethnic minority staff and patients, and take initiatives to reduce and, eventually, eradicate them.

Qualified Nurses' Perceptions of Cultural Competence and Experiences of Caring for Culturally Diverse Patients: A Qualitative Study in Four European Countries.

BACKGROUND: European nurses are expected to provide appropriate care for patients from diverse cultural backgrounds. However, there is limited knowledge and understanding of this process. The aim of this study was to analyse the perceptions of culture and experiences of caring for patients from diverse cultural backgrounds of a purposive sample of qualified nurses from four European countries, namely Belgium, Portugal, Spain and Turkey. METHODS: A qualitative phenomenological approach was selected in order to understand complex phenomena through the participants' lived experiences, meanings and perspectives. Individual interviews and focus groups took place with 28 staff nurses and 11 nurse managers from four European countries. The sociodemographic and cultural characteristics of the sample were described and analysed using descriptive statistics. Qualitative data were transcribed verbatim, translated into English and analysed following Braun and Clark's phases for thematic analysis. RESULTS: Five themes and twelve subthemes emerged from thematic analysis of the transcripts. The themes included: (1) relevance of culture for nursing; (2) culture in the healthcare service; (3) qualities of the healthcare professionals; (4) challenges to culturally competent care; (5) becoming a culturally competent nurse. CONCLUSIONS: There are challenges to the delivery of culturally congruent care, namely language and communication difficulties, prejudices and stereotyping in the health service, a tendency for ethnocentrism, a lack of education and training in cultural competence and a lack of support from the health service to facilitate new ways of acting.

How can the built environment affect the impact of autonomous vehicles' operational behaviour on air quality?

Autonomous vehicles (AVs) are pointed out as the technology that will reshape the concept of mobility, with significant implications for the economy, the environment, and society. This fact will bring new challenge to cities urban planning. Research to anticipate the AVs impacts, maximizing their benefits and reduce trade-offs are currently crucial. This work investigates the potential challenges and benefits of gradually replace internal combustion engine human driven vehicles with different penetration rates of AVs - 10%, 30%, 50%, 70%, 90%, and 100% - in urban roads of different characteristics, either in terms of traffic singularities or volumes, and its related implications on air quality. For that purpose, two urban areas with distinct features, Porto and Aveiro, were selected as case studies, and a modelling setup composed of a traffic model, an emission model, and a local air quality model was applied. The results revealed that the AVs benefits are directly linked with the urban design and the road characteristics. In the Aveiro case study, the AVs promoted positive changes with average reductions in daily NOx emissions (compared with the baseline scenario, without AVs) ranging between -2.1% (for C10%) and -7.7% (for C100%). In line with the emissions impacts, positive effects were found on air quality, with average reductions of NO2 concentrations up to -4% (for C100%). In Porto urban area, slight differences in NOx emissions were obtained (<2%), which implied no changes in the air quality levels. The distinct impact of AVs in the study areas is mostly explained by the traffic light coordination system and directional split distributions in the main roads. These results provide valuable insights to support decision-makers in the definition of strategies that allow the integration of these new emerging technologies in the road infrastructure, considering the features of the urban design, traffic profile and road characteristics.

Dyslipidemia Diagnosis and Treatment: Risk Stratification in Children and Adolescents.

Dyslipidemias or dyslipoproteinemias are quantitative changes in total cholesterol concentration, respective fractions, or triglycerides in the plasma. Evidence supported that dyslipidemia in childhood is associated with atherosclerosis in adulthood, and early identification and treatment potentially reduce cardiovascular risk in adulthood, which is the principal cause of morbidity and mortality in developed countries. Dyslipidemias can result from primary lipoprotein metabolism changes due to different genetic causes (primary dyslipidemias) or as a consequence of exogenous factors or other pathologies (secondary dyslipidemias). Therefore, the combined dyslipidemias result from the association of important epigenetic and environmental influences with risk factors for cardiovascular disease. The criterion for lipid metabolism screening at young ages is not widely accepted and possibly follows a universal or directed screening strategy. Additionally, little is known about its long-term effects or possible risk-benefit despite the growing tendency to start pharmacological therapy. Therefore, this study aimed to review the available bibliography on dyslipidemia in pediatric age to present a practical and structured approach to dyslipidemia that focuses on screening, risk stratification for atherosclerotic disease, and therapeutic approach.

Median arcuate ligament syndrome: A case report of a rare disease.

INTRODUCTION: Median arcuate ligament syndrome (MALS) is a rare condition caused by the compression of the celiac trunk by the median arcuate ligament, which may trigger a typical symptom triad: postprandial abdominal pain, weight loss, nausea and vomiting. CLINICAL CASE: A 58-year-old male was admitted to the emergency department due to abdominal pain, vomiting, fever and diarrhea. On admission, the patient was tachycardic, had abdominal distension, no peritoneal irritation signs, and a serum lactate level of 5 mmol/L. The computed tomography (CT) scan showed gastric and intestinal pneumatosis associated with pneumoportia. Conservative treatment with intravenous fluids, antibiotics and low molecular weight heparin, was initiated. The reassessment CT scan showed resolution of the gastric and intestinal pneumatosis and a severe stenosis of the initial portion of the celiac trunk with associated angulation. After recovery from the acute episode, an abdominal duplex ultrasound and an aortoiliac arteriography in forced inspiration and expiration was performed, corroborating the diagnosis of MALS. A laparoscopic decompression of the celiac trunk was performed. DISCUSSION: Symptoms of MALS closely mimic other abdominal disorders, and it should be considered in the differential diagnosis. Currently, there are no international guidelines on MALS diagnostic criteria. Treatment is focused on decompression of the median arcuate ligament constriction of the celiac artery, with or without celiac lymph node removal. CONCLUSION: MALS diagnostic and therapeutic approach must be patient focused. Laparoscopic decompression is an effective treatment and can provide immediate symptomatic relief, associated with the benefits of the less invasive nature of the procedure.

Increased Intake of Both Caffeine and Non-Caffeine Coffee Components Is Associated with Reduced NAFLD Severity in Subjects with Type 2 Diabetes.

Coffee may protect against non-alcoholic fatty liver disease (NAFLD), but the roles of the caffeine and non-caffeine components are unclear. Coffee intake by 156 overweight subjects (87% with Type-2-Diabetes, T2D) was assessed via a questionnaire, with 98 subjects (all T2D) also providing a 24 h urine sample for quantification of coffee metabolites by LC-MS/MS. NAFLD was characterized by the fatty liver index (FLI) and by Fibroscan® assessment of fibrosis. No associations were found between self-reported coffee intake and NAFLD parameters; however, total urine caffeine metabolites, defined as Σcaffeine (caffeine + paraxanthine + theophylline), and adjusted for fat-free body mass, were significantly higher for subjects with no liver fibrosis than for those with fibrosis. Total non-caffeine metabolites, defined as Σncm (trigonelline + caffeic acid + p-coumaric acid), showed a significant negative association with the FLI. Multiple regression analyses for overweight/obese T2D subjects (n = 89) showed that both Σcaffeine and Σncm were negatively associated with the FLI, after adjusting for age, sex, HbA1c, ethanol intake and glomerular filtration rate. The theophylline fraction of Σcaffeine was significantly increased with both fibrosis and the FLI, possibly reflecting elevated CYP2E1 activity-a hallmark of NAFLD worsening. Thus, for overweight/obese T2D patients, higher intake of both caffeine and non-caffeine coffee components is associated with less severe NAFLD. Caffeine metabolites represent novel markers of NAFLD progression.
