Breaking new ground: MASLD vs. MAFLD-which holds the key for risk stratification?

BACKGROUND: The classification and nomenclature of non-alcoholic fatty liver disease (NAFLD) has been the subject of ongoing debate in the medical community. Through the introduction of metabolic dysfunction-associated fatty liver disease (MAFLD) and the later release of metabolic dysfunction-associated steatotic liver disease (MASLD), the limitations associated with NAFLD are intended to be addressed. Both terminologies incorporate the metabolic component of the disease by providing diagnostic criteria that relies on the presence of underlying metabolic risk factors. MATERIALS AND METHODS: An epidemiologic cross-sectional study of individuals who had undergone abdominal ultrasound and vibration-controlled transient elastography (VCTE) as part of a routine check was performed. We evaluated clinical, anthropometric, and biochemical variables to determine the metabolic profile of each subject. RESULTS: The study included a total of 500 participants, 56.8% (n = 284) males and 43.2% (n = 216) females, with a mean age of 49 ± 10 years. 59.4% (n = 297) were diagnosed with MAFLD and MASLD, 10.2% (n = 51) were diagnosed only with MASLD and 30.4% (n = 152) were not diagnosed with either MAFLD or MASLD. The differences in prevalence were mainly based on the detection of individuals with a BMI < 25 kg/m2, where MASLD captures the largest number (p < 0.001). CONCLUSIONS: Although MASLD has a higher capture of lean patients compared to MAFLD, patients with MAFLD and MASLD have a worse metabolic profile than those with only MASLD. Our results provide evidence that MAFLD better identifies patients likely to have a higher risk of liver fibrosis and of disease progression.

Probiotic improves symptomatic and viral clearance in Covid19 outpatients: a randomized, quadruple-blinded, placebo-controlled trial.

Intestinal bacteria may influence lung homeostasis via the gut-lung axis. We conducted a single-center, quadruple-blinded, randomized trial in adult symptomatic Coronavirus Disease 2019 (Covid19) outpatients. Subjects were allocated 1:1 to probiotic formula (strains Lactiplantibacillus plantarum KABP022, KABP023, and KAPB033, plus strain Pediococcus acidilactici KABP021, totaling 2 × 109 colony-forming units (CFU)) or placebo, for 30 days. Co-primary endpoints included: i) proportion of patients in complete symptomatic and viral remission; ii) proportion progressing to moderate or severe disease with hospitalization, or death; and iii) days on Intensive Care Unit (ICU). Three hundred subjects were randomized (median age 37.0 years [range 18 to 60], 161 [53.7%] women, 126 [42.0%] having known metabolic risk factors), and 293 completed the study (97.7%). Complete remission was achieved by 78 of 147 (53.1%) in probiotic group compared to 41 of 146 (28.1%) in placebo (RR: 1.89 [95 CI 1.40-2.55]; P < .001), significant after multiplicity correction. No hospitalizations or deaths occurred during the study, precluding the assessment of remaining co-primary outcomes. Probiotic supplementation was well-tolerated and reduced nasopharyngeal viral load, lung infiltrates and duration of both digestive and non-digestive symptoms, compared to placebo. No significant compositional changes were detected in fecal microbiota between probiotic and placebo, but probiotic supplementation significantly increased specific IgM and IgG against Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV2) compared to placebo. It is thus hypothesized this probiotic primarily acts by interacting with the host's immune system rather than changing colonic microbiota composition. Future studies should replicate these findings and elucidate its mechanism of action (Registration: NCT04517422).Abbreviations: AE: Adverse Event; BMI: Body Mass Index; CONSORT: CONsolidated Standards of Reporting Trials; CFU: Colony-Forming Units; eDRF: Electronic Daily Report Form; GLA: Gut-Lung Axis; GSRS: Gastrointestinal Symptoms Rating Scale; hsCRP: High-sensitivity C-Reactive Protein; HR: Hazard Ratio; ICU: Intensive Care Unit; OR: Odds Ratio; PCoA: Principal Coordinate Analysis; RR: Relative Risk; RT-qPCR: Real-Time Quantitative Polymerase Chain Reaction; SARS-CoV2: Severe acute respiratory syndrome coronavirus 2; SpO2: Peripheral Oxygen Saturation; WHO: World Health Organization.

Coronaphobia among healthcare professionals in Mexico: A psychometric analysis.

The present study examined the validity of the coronaphobia phenomenon with healthcare professionals using a psychometric approach. Using SurveyMonkey, an adapted version of the Coronavirus Anxiety Scale-Healthcare version (CAS-HC) was administered to 231 adult healthcare professionals in Mexico. Confirmatory factor analysis demonstrated that dysfunctional coronavirus anxiety symptoms cohered into a reliable, single factor structure of coronaphobia. A receiver operating characteristic curve analysis indicated that the classification features of the CAS-HC were strong, but supported a less stringent cut-score for this population. Construct validity was supported by the positive correlations between the CAS-HC and measures of depression and generalized anxiety, while known groups validity was found with high CAS-HC scores exhibited by those working in emergency rooms, triage, and intensive care units. The findings collectively support the coronaphobia construct with healthcare professionals, and the finding that over one third of the participants in the study scored in the clinical range on this measure points to the critical importance of assessing and alleviating this form of distress in this vulnerable but indispensable workforce.

Long-standing effect of cholecystectomy in patients with metabolic-associated fatty liver disease.

OBJECTIVE: The role of cholecystectomy as a risk factor in patients with metabolic-associated fatty liver disease (MAFLD) remains unclear. This study aimed to investigate if long-standing cholecystectomy is associated with advanced liver fibrosis and cirrhosis in patients with recently diagnosed MAFLD. METHODS: A retrospective observational study was performed in four hospitals in Mexico including patients with recently diagnosed MAFLD and a history of cholecystectomy. Subjects were divided into those with cholecystectomy ≥6 months before MAFLD diagnosis (ChBM), and those with cholecystectomy at the time of MAFLD diagnosis (ChAM). Odds ratios (OR) for the association of advanced liver fibrosis and cirrhosis with the timing of cholecystectomy were calculated. RESULTS: Mean age of 211 participants was 49.06 ± 15.12 years and the majority were female (72.5%). Patients from the ChBM (n = 70) group were significantly older (53.14 vs. 47.03 years; P = 0.003), had higher BMI (30.54 vs. 28.52 kg/m2; P = 0.011) and lower platelet count (236.23 vs. 266.72 × 103/µL; P = 0.046) compared with patients from ChAM group (n = 141). In multivariable-adjusted analysis, age (OR = 2.37; P = 0.024), dyslipidemia (OR = 4.28; P = 0.005) and severe liver fibrosis (OR = 4.68; P = 0.0) were independent risk factors associated with long-standing cholecystectomy. CONCLUSION: Patients with long-standing cholecystectomy (≥6 months) are at increased risk of severe liver fibrosis and cirrhosis at the time of MAFLD diagnosis compared to those with recently done cholecystectomy. Advanced age (>50 years) and dyslipidemia are also commonly found in these subjects.

Interventions for pityriasis rosea.

BACKGROUND: Pityriasis rosea is a scaly, itchy rash that mainly affects young adults and lasts for 2 to 12 weeks. The effects of many available treatments are uncertain. This is an update of a Cochrane Review first published in 2007. OBJECTIVES: To assess the effects of interventions for the management of pityriasis rosea in any individual diagnosed by a medical practitioner. SEARCH METHODS: We updated our searches of the following databases to October 2018: the Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We searched five trials registers. We also checked the reference lists of included and excluded studies, contacted trial authors, scanned the abstracts from major dermatology conference proceedings, and searched the CAB Abstracts database. We searched PubMed for adverse effects to November 2018. SELECTION CRITERIA: Randomised controlled trials of interventions in pityriasis rosea. Treatment could be given in a single therapy or in combination. Eligible comparators were no treatment, placebo, vehicle only, another active compound, or placebo radiation treatment. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by the Cochrane. Our key outcomes were good or excellent rash improvement within two weeks, rated separately by the participant and medical practitioner; serious adverse events; resolution of itch within two weeks (participant-rated); reduction in itch score within two weeks (participant-rated); and minor participant-reported adverse events not requiring withdrawal of the treatment. MAIN RESULTS: We included 14 trials (761 participants). In general, risk of selection bias was unclear or low, but risk of performance bias and reporting bias was high for 21% of the studies. Participant age ranged from 2 to 60 years, and sex ratio was similar. Disease severity was measured by various severity indices, which the included studies did not categorise. Six studies were conducted in India, three in Iran, two in the Philippines, and one each in Pakistan, the USA, and China. The included studies were conducted in dermatology departments and a paediatric clinic. Study duration ranged from 5 to 26 months. Three studies were funded by drug manufacturers; most studies did not report their funding source. The included studies assessed macrolide antibiotics, an antiviral agent, phototherapy, steroids and antihistamine, and Chinese medicine. None of the studies measured participant-rated good or excellent rash improvement. All reported outcomes were assessed within two weeks of treatment, except for adverse effects, which were measured throughout treatment. There is probably no difference between oral clarithromycin and placebo in itch resolution (risk ratio (RR) 0.84, 95% confidence interval (CI) 0.47 to 1.52; 1 study, 28 participants) or rash improvement (medical practitioner-rated) (RR 1.13, 95% CI 0.89 to 1.44; 1 study, 60 participants). For this comparison, there were no serious adverse events (1 study, 60 participants); minor adverse events and reduction in itch score were not measured; and all evidence was of moderate quality. When compared with placebo, erythromycin may lead to increased rash improvement (medical practitioner-rated) (RR 4.02, 95% CI 0.28 to 56.61; 2 studies, 86 participants, low-quality evidence); however, the 95% CI indicates that the result may also be compatible with a benefit of placebo, and there may be little or no difference between treatments. Itch resolution was not measured, but one study measured reduction in itch score, which is probably larger with erythromycin (MD 3.95, 95% CI 3.37 to 4.53; 34 participants, moderate-quality evidence). In the same single, small trial, none of the participants had a serious adverse event, and there was no clear difference between groups in minor adverse events, which included gastrointestinal upset (RR 2.00, CI 0.20 to 20.04; moderate-quality evidence). Two trials compared oral azithromycin to placebo or vitamins. There is probably no difference between groups in itch resolution (RR 0.83, 95% CI 0.28 to 2.48) or reduction in itch score (MD 0.04, 95% CI -0.35 to 0.43) (both outcomes based on one study; 70 participants, moderate-quality evidence). Low-quality evidence from two studies indicates there may be no difference between groups in rash improvement (medical practitioner-rated) (RR 1.02, 95% CI 0.52 to 2.00; 119 participants). In these same two studies, no serious adverse events were reported, and there was no clear difference between groups in minor adverse events, specifically mild abdominal pain (RR 5.82, 95% CI 0.72 to 47.10; moderate-quality evidence). Acyclovir was compared to placebo, vitamins, or no treatment in three trials (all moderate-quality evidence). Based on one trial (21 participants), itch resolution is probably higher with placebo than with acyclovir (RR 0.34, 95% CI 0.12 to 0.94); reduction in itch score was not measured. However, there is probably a significant difference between groups in rash improvement (medical practitioner-rated) in favour of acyclovir versus all comparators (RR 2.45, 95% CI 1.33 to 4.53; 3 studies, 141 participants). Based on the same three studies, there were no serious adverse events in either group, and there was probably no difference between groups in minor adverse events (only one participant in the placebo group experienced abdominal pain and diarrhoea). One trial compared acyclovir added to standard care (calamine lotion and oral cetirizine) versus standard care alone (24 participants). The addition of acyclovir may lead to increased itch resolution (RR 4.50, 95% CI 1.22 to 16.62) and reduction in itch score (MD 1.26, 95% CI 0.74 to 1.78) compared to standard care alone. Rash improvement (medical practitioner-rated) was not measured. The trial reported no serious adverse events in either group, and there may be no difference between groups in minor adverse events, such as headache (RR 7.00, 95% CI 0.40 to 122.44) (all results based on low-quality evidence). AUTHORS' CONCLUSIONS: When compared with placebo or no treatment, oral acyclovir probably leads to increased good or excellent, medical practitioner-rated rash improvement. However, evidence for the effect of acyclovir on itch was inconclusive. We found low- to moderate-quality evidence that erythromycin probably reduces itch more than placebo. Small study sizes, heterogeneity, and bias in blinding and selective reporting limited our conclusions. Further research is needed to investigate different dose regimens of acyclovir and the effect of antivirals on pityriasis rosea.

[Recomendaciones sobre la utilización de las fórmulas infantiles con proteína aislada de soya en la alimentación del lactante. Documento de posición basado en la evidencia].

BACKGROUND: Soy infant formulas (SIF) have long been used as an alternative for infants with special nutritional requirements. However, the medical indications for their use, their allergenicity, safety and efficacy are still controversial. OBJECTIVE: To present recommendations for the use of SIF based on the existing literature. METHODS: We consulted systematic reviews and clinical practice guides, through validated search algorithms, and systems such as Appraisal of Guidelines for REsearch and Evaluation (AGREE)II and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). For the elaboration of the clinical recommendations, the most important topics were analyzed and discussed by the responsible researchers and the group of experts in the development of a position paper. The quality of the evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. RESULTS: Several reports with variable quality of evidence were found. They support SIF's efficacy in the management of cow's milk allergy and infant's digestive tolerance, as well as its low cross allergy compared to cow's milk and other formulas. We also found other studies that indicate the safety of SIFs on different nutritional, immune and developmental parameters. There is also evidence that demonstrates that SIFs have important advantages in terms of cost-benefit, palatability and effects on the intestinal microbiota, compared to other formulas. CONCLUSIONS: Although evidence to recommend its use in functional digestive disorders is limited, SIFs have an adequate safety profile and are still a valid option for infant feeding.

ANTECEDENTES: Las fórmulas a base de proteína de soya (FBPS) se han utilizado desde hace tiempo como una alternativa para lactantes con requerimientos nutricionales especiales. Sin embargo, las indicaciones médicas para su uso, su alergenicidad, seguridad y eficacia aún son controvertidas. OBJETIVO: Presentar recomendaciones del uso de FBPS basadas en la literatura existente. MÉTODOS: Se realizó la consulta de revisiones sistemáticas y guías de práctica clínica, por medio de algoritmos de búsqueda validados, y sistemas como AGREE (Appraisal of Guidelines for REsearch and Evaluation) II y PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Para la elaboración de las recomendaciones clínicas se analizaron y discutieron los tópicos de mayor importancia, por parte de los investigadores responsables y el grupo de expertos del desarrollo de un documento de posición. Se evaluó la calidad de la evidencia utilizando el sistema GRADE (Grading of Recommendations, Assessment, Development and Evaluation). RESULTADOS: Se encontraron distintos reportes con calidad de evidencia variable que sustentan la eficacia de las FBPS en el manejo de la alergia a la proteína de la leche de vaca y en la tolerancia digestiva del lactante, así como su baja alergia cruzada en comparación a la leche de vaca y otras fórmulas. También se encontraron otros estudios que indican la seguridad de las FBPS sobre distintos parámetros nutricionales, inmunitarios y de desarrollo. Existe además evidencia que demuestra que las FBPS tienen ventajas importantes en cuestión de costo-beneficio, palatabilidad y efectos sobre la microbiota intestinal, en comparación con otras fórmulas. CONCLUSIONES: Aunque existe evidencia limitada para recomendar su utilización en los trastornos digestivos funcionales, las FBPS tienen un perfil de seguridad adecuado y continúan siendo una opción válida para la alimentación del lactante.

Tracheal growth assessment in mongrel puppies (dogs) through multidetector CT.

The aim of this study was to describe the tracheal growth pattern and its zoometric relationship in related medium-sized mongrel puppies through adulthood. Fourteen puppies were studied. CT monitoring was performed monthly, starting in the 1st month of life through the 7th month and subsequently at the 9th and 12th months. Additionally, six zoometric measurements were performed. Dorsoventral (DV) and transverse (TV) diameters and the luminal area from C1 to T2 were obtained. The global tracheal growth pattern revealed an increase up to 13 times its initial size, reaching a plateau phase during the last trimester. The relationship between the DV and the TV internal diameters of the tracheal lumen did not change during growth. As previously reported, the cranial tracheal area was wider, while the caudal part gradually decreased towards T1-T2; this consideration is important since the more distal an endotracheal tube is inserted, the greater the risk that injury may occur. The linear correlation between the zoometric measurements and the tracheal ring areas was positive. This study provides evidence for the evaluation of the morphometry of the canine trachea during physiological growth using helicoidal CT as a non-invasive, accurate tool.

[Corrigendum] Death receptor 5 expression is inversely correlated with prostate cancer progression.

During the preparation of the figures in the above article, the authors inadvertently duplicated in Fig. 1B, a and b (high and low magnification images) the images that had already appeared as Figs. 5A, a and c (high and low magnification images), respectively, of the following paper: Huerta-Yepez S, Baritaki S, Baay-Guzman G, Hernandez-Luna MA, Hernandez-Cueto A, Vega MI and Bonavida B: Contribution of either YY1 or BclXL-induced inhibition by the NO-donor DETANONOate in the reversal of drug resistance, both in vitro and in vivo. Nitric Oxide 29: 17-24, 2013. The revised version of Fig. 1 containing the corrected data for Fig. 1B, a and b (high and low magnification images; the YY1 data) is shown opposite protein expression.

Efficacy of Lactobacillus reuteri DSM 17938 for infantile colic: Systematic review with network meta-analysis.

BACKGROUND: 5% to 40% of infants cry excessively, usually accompanied by fussiness and excessive of gas. There are no uniform criteria for treatment of infantile colic. Lactobacillus reuteri DSM 17938 has been used with promising results. The objective of this network-meta-analysis (NMA) is to compare the efficacy of L reuteri DSM 17938 with other interventions for infantile colic. METHODS: RCTs, published between 1960 and 2015 for the treatment of infantile colic were included. Primary outcome was duration of crying after 21 to 28 days of treatment. Different databases were searched. Information was analyzed using control group as central axis. A random effect model was used. Hedges standard mean difference (SMD) and odds ratio (OR) were calculated. A SUCRA analysis was performed to evaluate superiority for each intervention. RESULTS: 32 RCTs were analyzed, including 2242 patients. Studies with L reuteri DSM 17938 versus Ctrl., Diet versus Ctrl. and Acupuncture versus Ctrl. were the most influential studies in the NMA. L reuteri DSM 17938 [WMD -51.3 h (CI95% -72.2 to -30.5 h), P .0001] and dietetic approaches [WMD -37.4 h (CI95% -56.1 to -18.7 h), P .0001] were superior compared to the other treatments. CONCLUSIONS: L reuteri DSM 17938 and some dietetic approaches are better to other interventions for treatment of infantile colic.

[Rhino-Orbital Mucormycosis. Cohort study of its treatment according disease extent and reversion of its pathophysiology]. / Mucormicosis rinoorbitaria. Estudio de cohorte de su tratamiento de acuerdo a la extensión de la enfermedad y reversión de su fisiopatología.

Mucormycosis is a lethal opportunistic fungal infection, described mostly in immunocompromised patients. A comparative cohort study was conducted to compare the evolution of the study group patients with rhino-orbital mucormycosis, in which a therapeutic protocol was instituted, in which the pterygomaxillary fossa is systematically surgically approached and orbital exenteration is performed or not based on the spreading of the infection to the orbital apex or the orbital fissure, with a historical group where these criteria were not applied. Fifteen cases were included, eight in historic group A and seven in the study group B. Medical treatment was provided with control of the underlying disease (amphotericin B and low molecular weight heparin) as well as surgical treatment with extensive debridement including endoscopic ethmoidectomy and exploration of the pterygomaxillary fossa, also performing orbital exenteration only in patients who presented orbital apex syndrome in group B. In group A, there was a mortality rate of 50%, in group B all patients were clinical cured; however, the two patients with hematologic diseases died of complications not related to the fungal infection. With the standardization of a diagnostic and therapeutic protocol, good results in healing and survival of patients can be obtained.

[Characterization of adolescents and reason for the visit when attending the pediatric emergency department of the General Hospital Dr. Manuel Gea González]. / Caracterización de los adolescentes y motivo de consulta por el que acuden al Servicio de Urgencias Pediátricas del Hospital General Dr. Manuel Gea González.

RATIONALE: Emergency health care demanded by adolescents has increased due to a variety of specific disorders. AIMS: (1) Describe the frequency of emergency services utilization by adolescents; (2) Identify the reason for the visit; (3) Describe psychosocial and health features of patients; and (4) Describe information related to informed assent. MATERIAL AND METHODS: Observational, descriptive, and prospective study carried out in patients aged 12 to 18 years, treated in the emergency department of General Hospital "Dr. Manuel Gea Gonzalez ", between 2008 and 2009. Survey data as well as the HEADSS sociodemographic questionnaire was used. RESULTS: A total of 170 patients were included in the study. The average age was 14.1 years; 55% were female. The main reasons for consultation were trauma (32.9%), followed by non-surgical gastrointestinal pathologies (12.4%), acute abdomen (11.8%), psychiatric emergencies (10.6%), neurological (8.8%), infectious or gynecologic obstetrical (both 8.2%). In 81% of cases, relatives (mostly parents) were the ones who decided to take the patient to the emergency room. It is noteworthy that in 64% of cases the patients had previously gone to the emergency room. Of the patients, 72.4% reported not having regular medical care and the remaining reported that medical care was referred to once or twice a year. CONCLUSIONS: Among patients seeking emergency care, a significant proportion are teenagers. The causes are varied, with care ranging from posttraumatic aspects to psycho-behavioral disorders. There is minimal culture in this age group to agree about their own treatment through informed consent.

Myocutaneous sternocleidomastoid flap for reconstruction after the resection of a parapharyngeal heterotopic glioma in a child with cleft palate, and systematic review of parapharyngeal glial heterotopia.

We describe the surgery and reconstruction employed with a sternocleidomastoid myocutaneous flap for the treatment of a heterotopic glioma in a 2-year-old boy with incomplete palatal fissure who presented with dysphagia and snoring, in whom a lateral pharyngeal wall mass obstructing 60% of the airway was noted. Heterotopic gliomas are uncommonly reported in the parapharyngeal space and should be included in the differential diagnosis at this location in children. Parapharyngeal tumors present difficult diagnostic and management challenges; head and neck surgeons must be prepared not only for the resection but also for the reconstruction of these rare lesions.

Effects of Fructans from Mexican Agave in Newborns Fed with Infant Formula: A Randomized Controlled Trial.

BACKGROUND: The importance of prebiotics consumption is increasing all over the world due to their beneficial effects on health. Production of better prebiotics from endemic plants raises possibilities to enhance nutritional effects in vulnerable population groups. Fructans derived from Agave Plant have demonstrated their safety and efficacy as prebiotics in animal models. Recently, the safety in humans of two fructans obtained from Agave tequilana (Metlin(®) and Metlos(®)) was demonstrated. METHODS: This study aimed to demonstrate the efficacy as prebiotics of Metlin(®) and Metlos(®) in newborns of a randomized, double blind, controlled trial with a pilot study design. Biological samples were taken at 20 ± 7 days, and three months of age from healthy babies. Outcomes of efficacy include impact on immune response, serum ferritin, C-reactive protein, bone metabolism, and gut bacteria changes. RESULTS: There were differences statistically significant for the groups of infants fed only with infant formula and with formula enriched with Metlin(®) and Metlos(®). CONCLUSIONS: Our results support the efficacy of Metlin(®) and Metlos(®) as prebiotics in humans, and stand the bases to recommend their consumption. TRIAL REGISTRATION: ClinicalTrials.gov, NCT 01251783.

[Efficacy of racecadotril vs. smectite, probiotics or zinc as an integral part of treatment of acute diarrhea in children under five years: A meta-analysis of multiple treatments]. / Eficacia del racecadotrilo versus smectita, probióticos o zinc como parte integral del tratamiento de la diarrea aguda en menores de cinco años: meta-análisis de tratamientos múltiples.

RATIONALE: Despite major advances in treatment, acute diarrhea continues to be a public health problem in children under five years. There is no systematic approach to treatment and most evidence is assembled comparing active treatment vs. placebo. OBJECTIVE: Systematic review of evidence on efficacy of adjuvants for treatment of acute diarrhea through a network meta-analysis. METHODS: A systematic search of multiple databases searching clinical trials related to the use of racecadotril, smectite, Lactobacillus GG, Lactobacillus reuteri, Saccharomyces boulardii and zinc as adjuvants in acute diarrhea was done. The primary endpoint was duration of diarrhea. Information is displayed through network meta-analysis.The superiority of each coadjutant was analyzed by Sucra approach. RESULTS: Network meta-analysis showed race cadotril was better when compared with placebo and other adjuvants. Sucra analysis showed racecadotril as the first option followed by smectite and Lactobacillus reuteri. INTERPRETATION: Considering a strategic decision making approach, network meta-analysis allows us to establish the therapeutic superiority of racecadotril as an adjunct for the comprehensive management of acute diarrhea in children aged less than five years.

Barriers to lose weight from the perspective of children with overweight/obesity and their parents: a sociocultural approach.

INTRODUCTION: There are not enough studies about the barriers to lose weight from the perspective of children and their parents. METHODS: Children and adolescents diagnosed with overweight/obesity in the Department of Endocrinology and their parents were invited to participate in a series of focus group discussions (FGD). Twenty-nine children 10-16 years old and 22 parents participated in 7 focus groups; 2 mothers and 2 adolescents participated in depth interviews. All interviews were recorded, transcribed, and analyzed through grounded theory. RESULTS: Parents went to the hospital only when their children presented any obesity complication; for them, overweight was not a health problem. Parents referred to lack of time to supervise about a healthy diet and exercise; besides, the same parents, relatives, friends, and the mass media encourage the consumption of junk food. Children accepted eating a lot, not doing exercise, skipping meals, and not understanding overweight consequences. Both, parents and children, demanded support to do the time recommended for exercise inside the schools. They also suggested getting information from schools and mass media (TV) about overweight consequences, exercise, and healthy food by health workers; they recommended prohibiting announcements about junk food and its sale. CONCLUSIONS: The barriers detected were lack of perception of being overweight, its identification as a disease and its consequences, lack of time to supervise a healthy lifestyle, and a big social influence to eat junk food.

Death receptor 5 expression is inversely correlated with prostate cancer progression.

Prostate carcinoma (PCa) is one of the most common cancers in men. Prostate-specific antigen (PSA) has been widely used to predict the outcome of PCa and screening with PSA has resulted in a decline in mortality. However, PSA is not an optimal prognostic tool as its sensitivity may be too low to reduce morbidity and mortality. Consequently, there is a demand for additional robust biomarkers for prostate cancer. Death receptor 5 (DR5) has been implicated in the prognosis of several cancers and it has been previously shown that it is negatively regulated by Yin Yang 1 (YY1) in prostate cancer cell lines. The present study investigated the clinical significance of DR5 expression in a prostate cancer patient cohort and its correlation with YY1 expression. Immunohistochemical analysis of protein expression distribution was performed using tissue microarray constructs from 54 primary PCa and 39 prostatic intraepithelial neoplasia (PIN) specimens. DR5 expression was dramatically reduced as a function of higher tumor grade. By contrast, YY1 expression was elevated in PCa tumors as compared with that in PIN, and was increased with higher tumor grade. DR5 had an inverse correlation with YY1 expression. Bioinformatic analyses corroborated these data. The present findings suggested that DR5 and YY1 expression levels may serve as progression biomarkers for prostate cancer.

Diarrhea in preschool children and Lactobacillus reuteri: a randomized controlled trial.

OBJECTIVES: To evaluate whether daily administration of Lactobacillus reuteri DSM 17938 reduces the frequency and duration of diarrheal episodes and other health outcomes in day school children in Mexico. METHODS: Healthy children (born at term, aged 6-36 months) attending day care centers were enrolled in this randomized, double-blind, placebo-controlled trial. They received L reuteri DSM 17938 (dose 10(8) colony-forming unit; n = 168) or identical placebo (n = 168) by mouth, daily for 3 months, after which they were followed-up after a further 3 months without supplementation. RESULTS: Data from all children were included in the final analysis. L reuteri DSM 17938 significantly reduced the frequency and duration of episodes of diarrhea and respiratory tract infection at both 3 and 6 months (P < .05). Additionally, the number of doctor visits, antibiotic use, absenteeism from day school and parental absenteeism from work were significantly reduced in the L reuteri group (P < .05). A cost-benefit analysis revealed significant reductions in costs in the L reuteri-treated children. No adverse events related to the study product were reported. CONCLUSIONS: In healthy children attending day care centers, daily administration of L reuteri DSM 17938 had a significant effect in reducing episodes and duration of diarrhea and respiratory tract infection, with consequent cost savings for the community.

Treating BCG-induced disease in children.

BACKGROUND: Bacillus Calmette-Guerín (BCG) is a live attenuated vaccine to prevent tuberculosis, routinely administered at birth as part of the World Health Organization global expanded immunisation programme. Given intradermally, it can cause adverse reactions, including local, regional, distant and disseminated manifestations that may cause parental distress. Rarely, it can cause serious illness and even death. Among those patients with immunocompromised conditions, such as the human immunodeficiency virus (HIV) infection, the complication rate is even higher. OBJECTIVES: To assess the effects of different interventions for treating BCG-induced disease in children. SEARCH METHODS: The following databases were searched: the Cochrane Infectious Diseases Group Specialized Register and Cochrane Central Register of Controlled Trials (CENTRAL), published in The Cochrane Library (The Cochrane Library 2012, Issue 4); MEDLINE (1966 to November 2012); EMBASE (1947 to November 2012); and LILACS (1980 to November 2012). The metaRegister of Controlled Trials (mRCT) and the WHO trials search portal. Conference proceedings for relevant abstracts and experts were also contacted to identify studies. No language restrictions were applied. SELECTION CRITERIA: Randomized controlled trials (RCTs) comparing any medical or surgical treatment modality for BCG-induced disease in children. DATA COLLECTION AND ANALYSIS: Two authors independently evaluated titles, applied inclusion criteria, and assessed the risk of bias of studies. The primary outcomes were the failure rate of therapies for all types of BCG vaccine-induced complications and the time to resolution of illness measured in months. The secondary outcomes were death from BCG vaccine-induced disease and the all-cause mortality. Risk ratios (RRs) were used as measure of effect for dichotomous outcomes and mean differences for continuous outcomes. MAIN RESULTS: Five RCTs analysing 341 children addressed the primary outcomes and were included. Four arms compared oral antibiotics to no intervention or placebo, one arm evaluated needle aspiration compared to no intervention, and another evaluated the use of locally instilled isoniazid versus oral erythromycin.Two small studies evaluated oral isoniazid; we are uncertain of whether this intervention has an effect on clinical failure (RR 1.48; 95% Confidence Interval (CI) 0.79 to 2.78; 54 participants, two studies, very low quality evidence). Similarly, for oral erythromycin, we are uncertain if there is an effect (clinical failure RR 1.03; 95% CI 0.70 to 1.53; 148 participants, three studies, very low quality evidence), and for oral isoniazid plus rifampicin (clinical failure, RR 1.20; 95% CI 0.51 to 2.83; 35 participants, one study, very low quality evidence).In patients with lymphadenitis abscess, needle aspiration may reduce clinically persistent BCG-induced disease at 6 to 9 months of follow-up (RR 0.13; 95% CI 0.03 to 0.55; 77 participants, one study, low quality evidence). In another study of patients with the same condition, aspiration plus local instillation of isoniazid reduces time to clinical cure compared to aspiration plus oral erythromycin (mean difference 1.49 months less; 95% CI 0.82 to 2.15 less; 27 participants, one study).No RCTs of HIV-infected infants with a BCG-induced disease evaluated the use of antibiotics or other therapies for reducing the rate of clinical failure or the time to clinical resolution. No data on mortality secondary to the interventions for treating BCG-induced disease were reported. AUTHORS' CONCLUSIONS: It is unclear if oral antibiotics (isoniazid, erythromycin, or a combination of isoniazid plus rifampicin) are effective for the resolution of BCG-induced disease. Most non-suppurated lymphadenitis will resolve without treatment in 4 to 6 months. Patients with lymphadenitis abscess might benefit from needle aspiration and possibly local instillation of isoniazid could shorten recovery time. Included studies were generally small and could be better conducted. Further research should evaluate the use of needle aspiration and local instillation of isoniazid in fluctuant nodes. Therapeutic and preventive measures in HIV-infected infants could be important given the higher risk of negative outcomes in this group.
