Infectious events in patients with alopecia areata treated with JAK inhibitors: low burden and minimal impact on persistence in treatment.

BACKGROUND: Alopecia areata (AA) is a non-scarring disorder characterized by hair loss that greatly affects patients' quality of life and has a chronic, recurring course. This disease is marked by an inflammatory process, mainly on an autoimmune basis primarily regulated by Janus kinase (JAK). RESEARCH DESIGN AND METHODS: We conducted a retrospective study evaluating the safety of JAKi in a real-world setting in 91 AA patients, with a specific focus on the assessment of infectious events. RESULTS: Overall, 34 infectious events were observed in 28 patients (30.8%), among them 17 patients (60.7%) suspended treatment with JAKi until the infection was clinically resolved. Only in one case the infectious event led to a permanent discontinuation of the treatment. The data we observed in the study are consistent with results reported in clinical trials. CONCLUSION: It can be stated that, during treatment with JAKi in AA patients, infectious events may occur, but in most cases these events are easily manageable and do not result in permanent discontinuation of the drug.

Neophobia, sensory experience and child's schemata contribute to food choices.

PURPOSE: The aim of the present review is to analyze dynamic interactions between nutrigenomics, environmental cues, and parental influence, which can all lead to children's neophobic reactions and its persistence in time. METHODS: We reviewed studies available on electronic databases, conducted on children aged from birth to 18 years. We also considered official websites of Italian Institutions, providing advice on healthy eating during infancy. RESULTS: Modern day societies are faced with an eating paradox, which has severe and ever-growing implications for health. In face of a wider availability of healthy foods, individuals instead often choose processed foods high in fat, salt and sugar content. Economic reasons surely influence consumers' access to foods. However, there is mounting evidence that food choices depend on the interplay between social learning and genetic predispositions (e.g., individual eating traits and food schemata). Neophobia, the behavioral avoidance of new foods, represents an interesting trait, which can significantly influence children's food refusal. Early sensory experiences and negative cognitive schemata, in the context of primary caregiver-child interactions, importantly contribute to the priming of children's food rejection. CONCLUSIONS: As neophobia strongly affects consumption of healthy foods, it will be relevant to rule definitively out its role in the genesis of maladaptive food choices and weight status in longitudinal studies tracking to adulthood and, in meanwhile, implement early in life effective social learning strategies, to reduce long-term effects of neophobia on dietary patterns and weight status. LEVEL OF EVIDENCE: Level II, controlled trials without randomization.

In Situ Use of Mining Substrates for Wetland Construction: Results of a Pilot Experiment.

This paper evaluates an experimental wetland as part of a pilot soil reclamation project in a mining area. The wetland was constructed using materials of mining origin from the area; most reactive materials of acid pH were stabilised using limestone filler. The study selected macrophytes that are tolerant to potentially toxic elements (PTEs) and resistant to salinity, namely Phragmites australis, Juncus effusus, and Iris pseudacorus. These macrophytes were then placed in pots containing substrates composed of different mixtures of topsoil, peat, and mining waste (black or yellow sand). A thorough analysis of the physicochemical and mineralogical characteristics of the materials included studies of PTE mobilisation. This study emphasises the significance of the rhizosphere in directing the transfer of PTEs to the plant and the correlation between the substrate and the development of plant defence mechanisms, such as the formation of Fe-plates. Scanning electron microscopy was used to highlight these aspects and validate the results of the analytical determinations. These wetlands can be proposed as a phytoremediation strategy for areas affected by mining and maritime influence. They are easy to construct and remain stable, providing important ecosystem services such as the natural attenuation of acid mine drainage, support for vegetation development and fauna, and a clean ecosystem.

DNA methylation profiling of myelodysplastic syndromes and clinical response to azacitidine: A multicentre retrospective study.

Real-world data have revealed that a substantial portion of patients with myelodysplastic syndromes (MDS) does not respond to epigenetic therapy with hypomethylating agents (HMAs). The cellular and molecular reasons for this resistance to the demethylating agent and biomarkers that would be able to predict the treatment refractoriness are largely unknown. In this study, we shed light on this enigma by characterizing the epigenomic profiles of patients with MDS treated with azacitidine. Our approach provides a comprehensive view of the evolving DNA methylation architecture of the disease and holds great potential for advancing our understanding of MDS treatment responses to HMAs.

Complete remission with histamine blocker in a patient with intractable hyperadrenergic postural orthostatic tachycardia syndrome secondary to long coronavirus disease syndrome.

The COVID-19 pandemic caused by the novel severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), has emerged as a global public health concern and its sequels have barely started to outcrop. A good percentage of patients who suffered from COVID-19 are prone to develop long-COVID or post-COVID condition (PCC), a multisystemic, heterogeneous, chronic disorder. Patients with PCC may experience diverse manifestations, of which cardiovascular and neurological symptoms are among the most frequently reported. Indeed, dysautonomia presented as orthostatic intolerance has gained room following recent reports linking postural orthostatic tachycardia syndrome (POTS) with PCC. Disturbances in heart rate (HR) and blood pressure (BP) during postural changes are the cornerstones of orthostatic intolerance seen in patients suffering from PCC. A subtype of POTS, hyperadrenergic POTS, has been widely studied because of its association with mast cell activation syndrome (MCAS). Although a causative relationship between PCC, hyperadrenergic POTS, and MCAS remains unrevealed, these syndromes can overlap. We want to propose here a correlation produced by a close-loop mechanism with positive feedback established after SARS-CoV-2 infection in a previously healthy young patient.

Sarcopenic obesity and the impact on bone health.

PURPOSE OF REVIEW: Sarcopenic obesity is a newly identified pathological entity defined by an increase in body fat mass with an associated sarcopenia, characterized by loss of muscle mass, strength, and function. Recently, the concomitant presence of skeletal alteration with sarcopenic obesity has been described leading to a new clinical entity defined osteosarcopenic obesity (OSO). Many studies have tried to unravel the metabolic complex mechanism leading to this clinical entity in order to understand the pathophysiology of this complex condition with the aim of posing an early diagnosis to improve the therapeutic approaches. The purpose of this narrative review is to highlight and revise recent studies on this issue. RECENT FINDINGS: Recent research in the field of OSO has highlighted the role of nutrition and physical activity in the development and management of these conditions. While molecular and cellular pathways remain partially understood, there is a growing focus on lifestyle interventions as key factors in reducing the impact of OSO. These studies emphasize the need for early diagnosis and appropriate therapeutic strategies to improve quality of life and decrease morbidity and mortality associated with OSO. SUMMARY: Although the pathophysiological pathways underlying OSO are not fully understood, the clinical implications underscore the need for expanded research in this field. This research is crucial for enabling early diagnosis and implementing effective therapeutic interventions, with the goal of reducing morbidity and mortality and enhancing quality of life.

Food Compass and the challenge of sustainability on the route towards healthful diets.

In order to tackle the global increase in overweight and obesity prevalence, several nutrient profiling systems have been developed; among others, Food Compass Score (FCS) has been designed to encompass multiple domains of food healthfulness. However, environmental sustainability of healthy diets is another crucial dimension which should not be overlooked in the context of human health. The aim of the present study is to assess the association between healthiness and environmental sustainability of food items, using the FCS and Agribalyse databases, respectively. A total of 806 matching food items were identified, grouped in 12 food categories; within each category, differences in median Z-scores between FCS and Single Environmental Footprint (EF) Score were assessed. While Fruits, Legumes and Nuts, Mixed foods, Meat Poultry and Eggs (MPE), Savory and Sweets, and Vegetables showed statistically significant differences (all p < 0.001), Beverages (p = 0.361), Dairy (p = 0.092), Fats and Oils (p = 0.594), Grains (p = 0.436), Sauce and Condiments (p = 0.093), and Seafood (p = 0.241) had similar Food Compass and Single EF Z-scores distributions. These findings underscore a relevant lack of difference between healthfulness and environmental impact of some prominent food categories, such as Grains and Seafood. Therefore, we suggest matching nutrient profiling systems with adequate environmental sustainability indices.

A case report of LAI two injection start in a 16-year-old adolescent with severe manic episode and comorbid cannabinoid use disorder.

There is a lack of randomized clinical trials and few studies regarding long-acting injectable antipsychotics (LAIs) in adolescents. Non-adherence, aggressiveness, comorbid substance use disorder and lack of insight may represent the main reasons for starting LAIs. Hereby we describe a 16-year-old male adolescent subject with bipolar type I disorder and comorbid cannabinoid use disorder, successfully treated with two-injection start regimen of LAI aripiprazole. Two-injection start regime of aripiprazole could represent an effective and safe therapeutic option for adolescents with early onset bipolar disorder.

Symptomatic gallstone disease: Recurrence patterns and risk factors for relapse after first admission, the RELAPSTONE study.

BACKGROUND: Delayed cholecystectomy in patients with symptomatic gallstone disease is associated with recurrence. Limited data on the recurrence patterns and the factors that determine them are available. OBJECTIVE: We aimed to determine the pattern of relapse in each symptomatic gallstone disease (acute pancreatitis, cholecystitis, cholangitis, symptomatic choledocholithiasis, and biliary colic) and determine the associated factors. METHODS: RELAPSTONE was an international multicenter retrospective cohort study. Patients (n = 3016) from 18 tertiary centers who suffered a first episode of symptomatic gallstone disease from 2018 to 2020 and had not undergone cholecystectomy during admission were included. The main outcome was relapse-free survival. Kaplan-Meier curves were used in the bivariate analysis. Multivariable Cox regression models were used to identify prognostic factors associated with relapses. RESULTS: Mean age was 76.6 [IQR: 59.7-84.1], and 51% were male. The median follow-up was 5.3 months [IQR 2.1-12.4]. Relapse-free survival was 0.79 (95% CI: 0.77-0.80) at 3 months, 0.71 (95% CI: 0.69-0.73) at 6 months, and 0.63 (95% CI: 0.61-0.65) at 12 months. In multivariable analysis, older age (HR = 0.57; 95% CI: 0.49-0.66), sphincterotomy (HR = 0.58, 95% CI: 0.49-0.68) and higher leukocyte count (HR = 0.79; 95% CI: 0.70-0.90) were independently associated with lower risk of relapse, whereas higher levels of alanine aminotransferase (HR = 1.22; 95% CI: 1.02-1.46) and multiple cholelithiasis (HR = 1.19, 95% CI: 1.05-1.34) were associated with higher relapse rates. CONCLUSION: The relapse rate is high and different in each symptomatic gallstone disease. Our independent predictors could be useful for prioritizing patients on the waiting list for cholecystectomies.

Zinner syndrome in pediatric patients: rare disease leading to challenging management.

Introduction: Zinner syndrome (ZS) is the association of seminal vesicle cysts, ipsilateral ejaculatory duct obstruction, and ipsilateral renal agenesis. This condition is very rare in children and both diagnosis and treatment may be challenging. We reviewed the clinical presentation and treatment describing our experience with a series of three patients. Methods: From January 2016 to January 2021, three patients (patients 1, 2, and 3) with symptomatic ZS, aged 2, 15, and 17 years, respectively, were diagnosed and treated. All three patients were symptomatic, manifesting pelvic pain and dysuria. The diagnosis was made by physical examination, ultrasonography, and abdominopelvic MRI. Patient 1 underwent open surgery, while for patients 2 and 3, laparoscopic excision was performed. Results: The renal agenesis regarded the left side in patients 1 and 3, and the right side in patient 2. In all cases, the cystic complex was excised. The mean operating time was 4 h and the mean hospitalization time was 5 days (range 4-6 days). The mean follow-up period was 5 years (range 2-5 years). Patients 1 and 3 showed a complete resolution of the symptoms during postoperative follow-up. In patient 2, clinical symptoms relapsed because of the persistence of a 9 mm cyst requiring a redo laparoscopic excision. Conclusions: Seminal vesicle cyst with ipsilateral renal agenesis, even if rare in pediatric age, should be suspected in young male patients presenting with pelvic cystic masses, pelvic pain, dysuria, and ipsilateral renal absence. Conservative management should be reversed to asymptomatic patients. Surgical treatment is mandatory in symptomatic cases and the preferred approach is minimally invasive surgery to magnify the operating field to spare anatomical structures, primarily the contralateral vas deferens. Radicality is crucial to avoid the persistence of symptoms and the need for reintervention.

Analysis of internal heat recovery capability in air-cooled indirect fired GAX-based absorption chiller in part-load operation.

Single-effect absorption chillers are the most popular because of their low cost, despite their low COP. Among them, GAX-based AirCooled absorption chillers are very interesting because they have improved COP because of their ability to recover internal heat at low thermal lifts. This workshop analysed the ability of these types of chillers to recover internal heat at high thermal lifts by changing the pressure drop of an extra valve, a feature of the Robur absorption chiller when operating in subzero applications. The complete differential mathematical model analyses the components involved in heat supply and recovery and provides information on their operation. A thorough assessment of exergy destruction in the absorption refrigeration system was carried out. The main results show that when the chiller is driven at a temperature of 210 °C and an ambient temperature of 40 °C, a rise in the pressure drop of the additional valve, ΔPval1, from 175 to 700 kPa causes the extension of the vapour purification process to be reduced by 13.7% in the column of distillation and by 70.6% in the rectifier. Despite the adverse effect of ΔPval1 increase on the cooling capacity, there is no risk that the distillation column operates in weeping mode. However, this adjustment increases the internal thermal load of the generator by 26.9%. Furthermore, the mass fraction of the refrigerant flow is very similar. In addition, the occurrence of a two-phase solution flow at the input of a solution cooling absorber is the practical upper limit of ΔPval1. The refrigerant flow in the solution cooling absorber is reduced by 21.3%. Finally, the contribution of the heat recovery loop to the total exergy destruction in the refrigeration system rises slightly by 2.7% when ΔPval1 increases due to the contribution of the vapour purification system, which increases at the expense of that of the re-boiler and the SolutionCooled absorber. The results of this study show to what extent the modified GAX-based cycle can function effectively at high thermal lifts.

3D-4K Exoscope-Assisted CO2 Laser Supraglottoplasty for Severe Laryngomalacia in a Pediatric Patient.

Laryngomalacia is the most frequent congenital laryngeal anomaly. Surgery is possible by means of cold knife, carbon dioxide (CO2 ) laser, microdebrider and coblation, traditionally under microscopic view. We here describe the use of the 3D-4K exoscope assisted CO2 laser supraglottoplasty in tubeless general anesthesia in spontaneous breathing in a 5 month-old patient with severe laryngomalacia. Laryngoscope, 134:1359-1362, 2024.

Nutritional and metabolic aspects related to vulvodynia: What do we really know?

OBJECTIVES: Vulvodynia is an emerging health problem, still insufficiently studied, that causes a significant reduction in quality of life in many women and individuals assigned female sex at birth. Little is known about the effects of diet and metabolic disorders on this condition. The objective of this study was to review currently available evidence on the diet and the nutritional and metabolic status of patients affected by vulvodynia. METHODS: Published articles were systematically searched in the PubMed, Scopus, and Web of Science databases. RESULTS: The few available studies that reported data on patients' body mass index (BMI) described a BMI within the normal range in most patients affected by vulvodynia, showing no difference or a slightly lower BMI with respect to control individuals. Data on the relationship between metabolic diseases and vulvodynia are lacking. Regarding nutrition, the few available data do not support the prescription of a low-oxalate diet in women with vulvodynia. To date, studies on other dietary behaviors are also lacking. CONCLUSIONS: This review emphasizes-for the first time, to our knowledge-the lack of data and the importance of conducting prospective studies investigating the nutritional and metabolic aspects related to the onset, maintenance, and therapy of vulvodynia.

Dieting, obsessive-compulsive thoughts, and orthorexia nervosa: Assessing the mediating role of worries about food through a structural equation model approach.

BACKGROUND: Orthorexia Nervosa (ON) is a condition characterized by an obsessive focus on healthy eating, inflexible dietary rules, and persistent preoccupations with food. Despite it has been recently the subject of increasingly relevant studies, little is known about the mechanisms that might foster ON symptoms. OBJECTIVE: This study used a structural equation modeling approach to test the mediating effect of thoughts, worries, and preoccupations about food on the relationship that eating disorders (EDs) attitudes (e.g., dieting) and obsessive-compulsive thoughts and symptoms have with ON in a large community sample. It was hypothesized that the effect of dieting and obsessive-compulsive thoughts and symptoms on ON would be partially mediated by the presence of thoughts, worries, and preoccupations about food. METHODS: Data from a cross-sectional sample of 1328 participants (females = 976) recruited from the general population were asked to fill in an online survey comprising the Eating Attitude Test-26 (EAT-26), the Obsessive-compulsive subscale of the Symptom Checklist-90 Revised (SCL-90R-OC) and the Orthorexia Scale-15 (ORTO-15). RESULTS: Structural equation models indicated that both obsessive-compulsive thoughts and symptoms and dieting had a direct effect on ON and that food preoccupation partially mediated these relationships. CONCLUSION: These findings provide novel insight into the nature of ON that could aid its conceptualization and treatment.

The role of neighborhood inequalities on diabetes prevention care: a mini-review.

An emerging research niche has focused on the link between social determinants of health and diabetes mellitus, one of the most prevalent non-communicable diseases in modern society. The aim of the present mini-review is to explore and summarize current findings in this field targeting high-income countries. In the presence of disadvantaged neighborhood factors (including socioeconomic status, food environment, walkability and neighborhood aesthetics), diabetes prevention and care are affected at a multidimensional level. The vast majority of the included studies suggest that, besides individual risk factors, aggregated neighborhood inequalities should be tackled to implement effective evidence-based policies for diabetes mellitus.

Identification of a HIV-1 circulating BF1 recombinant form (CRF75_BF1) of Brazilian origin that also circulates in Southwestern Europe.

Introduction: The high recombinogenic potential of HIV-1 has resulted in the generation of countless unique recombinant forms (URFs) and around 120 reported circulating recombinant forms (CRFs). Here we identify through analyses of near full-length genomes (NFLG) a new HIV-1 CRF derived from subtypes B and F1. Methods: HIV-1 protease-reverse transcriptase (Pr-RT) sequences were obtained by RT-PCR amplification from plasma RNA. Near full-length genome sequences were obtained after amplification by RT-PCR in 5 overlapping fragments. Phylogenetic sequence analyses were performed via maximum likelihood. Mosaic structures were analyzed by bootscanning and phylogenetic analyses of genome segments. Temporal and geographical estimations of clade emergence were performed with a Bayesian coalescent method. Results: Through phylogenetic analyses of HIV-1 Pr-RT sequences obtained by us from samples collected in Spain and downloaded from databases, we identified a BF1 recombinant cluster segregating from previously reported CRFs comprising 52 viruses, most from Brazil (n = 26), Spain (n = 11), and Italy (n = 9). The analyses of NFLG genomes of 4 viruses of the cluster, 2 from Spain and 2 from Italy, allowed to identify a new CRF, designated CRF75_BF1, which exhibits a complex mosaic structure with 20 breakpoints. All 4 patients harboring CRF75_BF1 viruses studied by us had CD4+ T-cell lymphocyte counts below 220/mm3 less than one year after diagnosis, a proportion significantly higher (p = 0.0074) than the 29% found in other patients studied in Spain by us during the same period. The origin of the clade comprising CRF75_BF1 and related viruses was estimated around 1984 in Brazil, with subsequent introduction of CRF75_BF1 in Italy around 1992, and migration from Italy to Spain around 1999. Conclusion: A new HIV-1 CRF, designated CRF75_BF1, has been identified. CRF75_BF1 is the 6th CRF of South American origin initially identified in Western Europe, reflecting the increasing relationship of South American and European HIV-1 epidemics. The finding of low CD4+ T-cell lymphocyte counts early after diagnosis in patients harboring CRF75_BF1 viruses warrants further investigation on the virulence of this variant.

Epidemiology and treatment of renal anaemia in Spain: RIKAS retrospective study.

BACKGROUND AND OBJECTIVE: Studies on the prevalence of anaemia in chronic kidney disease in adults not on dialysis (CKD-ND) and in dialysis programmes (CKD-D) in Spain are not recent or focus on certain subgroups. The aim of this study was to know the epidemiology and current treatment patterns of anaemia associated with CKD in Spain. MATERIALS AND METHODS: Multicentre, non-interventional, retrospective study with CKD-ND stage 3a-5 and CKD-D patients treated in Spain between 2015 and 2017 (RIKAS study). RESULTS: The prevalence of anaemia in CKD-ND and CKD-D in 2015 was 33.8% and 91.5%, respectively, with similar results during 2016-2017. The prevalence of systemic inflammation in anaemic patients (18.1% and 51.8% for CKD-ND and CKD-D, respectively) was higher, especially in those treated with erythropoiesis-stimulating agents (ESA), compared to the general population with CKD-ND. After 12 months of follow-up, mean ferritin and transferrin saturation index (TSI) values in anaemic patients with CKD-ND were 187.1 ng/mL and 22.2%, respectively, while in CKD-D were 254.6 ng/mL and 20.2%. In ESA-treated patients, mean values were 190.6 ng/mL and 22.0% in ND-CKD, and 255.0 ng/mL and 20.2% in D-CKD. CONCLUSIONS: The prevalence of anaemia and inflammation increased with the disease severity, being higher in D-CKD. Iron parameters in anaemic patients treated or not with ESA are insufficient according to the guidelines, so there is room for improvement in the treatment of anaemia associated with CKD.

The incidence and risk factors of selected drug prescriptions and outpatient care after SARS-CoV-2 infection in low-risk subjects: a multicenter population-based cohort study.

Background: Knowledge about the dynamics of transmission of SARS-CoV-2 and the clinical aspects of COVID-19 has steadily increased over time, although evidence of the determinants of disease severity and duration is still limited and mainly focused on older adult and fragile populations. Methods: The present study was conceived and carried out in the Emilia-Romagna (E-R) and Veneto Regions, Italy, within the context of the EU's Horizon 2020 research project called ORCHESTRA (Connecting European Cohorts to increase common and effective response to SARS-CoV-2 pandemic) (www.orchestra-cohort.eu). The study has a multicenter retrospective population-based cohort design and aimed to investigate the incidence and risk factors of access to specific healthcare services (outpatient visits and diagnostics, drug prescriptions) during the post-acute phase from day-31 to day-365 after SARS-CoV-2 infection, in a healthy population at low risk of severe acute COVID-19. The study made use of previously recorded large-scale healthcare data available in the administrative databases of the two Italian Regions. The statistical analysis made use of methods for competing risks. Risk factors were assessed separately in the two Regions and results were pooled using random effects meta-analysis. Results: There were 35,128 subjects in E-R and 88,881 in Veneto who were included in the data analysis. The outcome (access to selected health services) occurred in a high percentage of subjects in the post-acute phase (25% in E-R and 21% in Veneto). Outpatient care was observed more frequently than drug prescriptions (18% vs. 12% in E-R and 15% vs. 10% in Veneto). Risk factors associated with the outcome were female sex, age greater than 40 years, baseline risk of hospitalization and death, moderate to severe acute COVID-19, and acute extrapulmonary complications. Conclusion: The outcome of interest may be considered as a proxy for long-term effects of COVID-19 needing clinical attention. Our data suggest that this outcome occurs in a substantial percentage of cases, even among a previously healthy population with low or mild severity of acute COVID-19. The study results provide useful insights into planning COVID-19-related services.
