Differences in body dissatisfaction between individuals with and without stigma toward obesity: A study of preadolescents and adolescents.

INTRODUCTION: Previous studies have focused on understanding the biopsychosocial implications of obesity stigma and have made proposals to minimize its negative consequences, as well as recommendations to eliminate or reduce this stigma; however, knowing which individuals stigmatize obesity and why will allow us to have a broader picture of stigmatization and thus help in planning interventions with greater impact. OBJECTIVE: The aims were to describe the stigmatization toward obesity in preadolescents and adolescents and to determine whether there are differences in body dissatisfaction, abnormal eating behaviors and self-esteem among those with and without stigma toward obesity. METHODS: A total of 307 preadolescents and 349 adolescents answered a set of questionnaires that evaluated abnormal eating behaviors, body dissatisfaction, self-esteem and stigma. RESULTS: Fifty-nine percent of the participants stigmatized individuals with obesity, with preadolescents having the greatest stigma levels. Differences were observed only in body dissatisfaction, where the group of preadolescents who stigmatized individuals with obesity and the group of adolescents who did not stigmatize individuals with obesity reported higher levels of body dissatisfaction. CONCLUSION: Obesity is stigmatized at early ages, regardless of sex; however, preadolescents with stigma toward obesity and adolescents without stigma toward obesity have greater body dissatisfaction, indicating that body dissatisfaction plays a crucial role in the stigmatization of obesity. LEVEL OF EVIDENCE: Level V, cross-sectional analytical study.

Obesity hypoventilation syndrome, literature review.

Obesity is a global health concern that has been increasing over the years, and it is associated with several pathophysiological changes affecting the respiratory system, including alveolar hypoventilation. Obesity hypoventilation syndrome (OHS) is one of the six subtypes of sleep-hypoventilation disorders. It is defined as the presence of obesity, chronic alveolar hypoventilation leading to daytime hypercapnia and hypoxia, and sleep-disordered breathing. The existence of a sleep disorder is one of the characteristics that patients with OHS present. Among them, 90% of patients have obstructive sleep apnea (OSA), and the remaining 10% of patients with OHS have non-obstructive sleep hypoventilation without OSA or with mild OSA. This review aims to provide a comprehensive understanding of the epidemiological and pathophysiological impact of OHS and to highlight its clinical features, prognosis, and severity, as well as the available treatment options.

Usual interstitial pneumopathy in a patient with hypersensitivity pneumonitis and microscopic polyangiitis. Case report.

One of the most frequent diffuse interstitial lung diseases is hypersensitivity pneumonitis. It is related to exposure to diverse antigens, causing fibrosis in advanced stages, making the differential diagnosis with interstitial pulmonary fibrosis difficult as it overlaps with the usual interstitial pneumonia pattern. On the other hand, there are interstitial lung diseases associated with ANCA, such as microscopic polyangiitis, which is also related to the usual interstitial pneumonia pattern. We present the case of a 74-year-old male patient with chronic dyspnea, history of smoking and exposure to organic particles, in addition to a pattern suggestive of moderately severe restriction. The diagnosis was confirmed by histology of hypersensitivity pneumonitis by presenting granules, however, anti MPO and p-ANCA positivity was found, integrating the simultaneous diagnosis of microscopic polyangiitis. This is a case of difficult diagnosis since these pathologies have not been previously reported to coexist.

Exploratory study of the prevalence of food addiction and its relationship with executive functioning, depression, and reinforcement sensitivity in a sample of Mexican adults.

Introduction: The study of food addiction (FA) has become relevant due to its high prevalence, the negative impact on quality of life, and its association with neuropsychological and psychiatric symptoms. Several studies have provided scientific support for these associations, however, the results are contradictory. Additionally, studies have unsuccessfully elucidated the true nature of the failures in executive functioning in people with FA symptomatology, particularly when it comes to executive deficits. Therefore, the purpose of this research was to establish whether the presence of executive dysfunction, depressive symptoms and binge eating problems, as well as high reward sensitivity entails a greater severity in FA traits and high body mass index (BMI) in a sample of Mexican adults. Methods: The sample consisted of Mexican men and women between 21-59 years (n = 36); who completed self-report questionnaires and performance tests to measure the study variables. Additionally, BMI was estimated with self-reported height and weight. Results: Our results showed that a high number of FA symptoms were associated with higher executive dysfunction scores, greater reward sensitivity, and more severe depressive and binge eating problems. Furthermore, factors that are more strongly associated with higher scores of FA include severe executive deficits, greater activation of the punishment avoidance system, and persistence in the search for reward when the depressive symptoms increased. The factors that best explained changes in the estimated BMI of women were a decreased crystallized intellectual capacity and the inability to control food intake as the number of FA symptoms increased. Discussion: In summary, the cognitive functioning profile characterized by general failure of the executive functioning, as well as a greater activation of the Punishment Avoidance System and persistence in the search for reward, were associated with greater severity of FA symptoms, especially when the depressive symptomatology was severe. In parallel, the psychopathology in participants associated with FA confirms the contribution of anxious and depressive symptomatology and borderline personality traits which could facilitate the expression of clinically relevant FA symptoms in women. Finally, we found that decreased crystallized intellectual capacity and inability to control food intake were linked to higher BMI when the number of FA symptoms increased.

Terapia de remediación cognitiva en bulimia nerviosa: Un estudio de caso / Cognitive remediation therapy in bulimia nervosa: A case study

Resumen El objetivo de este estudio fue realizar una evaluación preliminar de la terapia de remediación cognitiva (TRE) en una paciente con bulimia nerviosa (BN). Bajo un diseño pre-post-tratamiento, la paciente (20 años de edad e índice de masa corporal [IMC] de 22.41) completó cuatro pruebas neuropsicológicas, tres medidas de síntomas de BN y dos de sintomatología psiquiátrica (depresión y ansiedad). Con base a las puntuaciones pre y post TRE fue calculado el cambio clínico objetivo (CCO). Los principales efectos neuropsicológicos se registraron en: flexibilidad de pensamiento, proceso visocontructivo, coherencia central y planificación (CCO = 0.39-0.99). También se identificaron cambios relevantes en las medidas de sintomatología psiquiátrica y de BN (CCO = 0.53-0.88), no así en el IMC. Este estudio suma evidencias respecto a la utilidad de la CRT en el tratamiento multidisciplinario, ya no solo de la anorexia nerviosa, sino que extiende su aplicabilidad a la BN.

Abstract The aim of this study was to perform a preliminary evaluation of cognitive remediation therapy (CRT) in a patient with bulimia nervosa (BN). The participant was 20 years old with a 22.41kg/m2 body mass index (BMI). Under a pre-post treatment design, the patient was administered four neuropsychological tests, three measures of BN symptoms and two of psychiatric symptomatology (depression and anxiety). Based on the pre and post CRT scores, the objective clinical change (OCC) was calculated. The main neuropsychological effects were observed in cognitive flexibility, visoconstructive processing (memory and central coherence) and working memory (OCC = 0,39-0,99). Relevant changes were also identified in the measures of psychiatric symptomatology and BN (OCC = 0,53-0,88), with no change in BMI. This study adds evidence regarding the usefulness of CRT in the multidisciplinary treatment not only of anorexia nervosa, but also extends its applicability to another eating disorder, BN.

Transdiagnostic factors in symptoms of depression and post-traumatic stress: a systematic review.

The current systematic review sought to identify quantitative empirical studies that focused on the transdiagnostic factors of intolerance of uncertainty, emotional dysregulation and rumination, and their relation with depression and post-traumatic stress disorder (PTSD). The overall research aim was to examine the relationship between these transdiagnostic factors and their relation with depression and PTSD symptoms. The systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Out of the 768 articles initially identified, 55 met the inclusion criteria for the current review. The results determined that intolerance of uncertainty is indirectly related to depression and PTSD symptoms, mainly through other factors including emotion dysregulation and rumination. Additionally, emotional dysregulation is a significant predictor of both depression and PTSD symptoms. Rumination is a robust factor related to depression and PTSD symptoms, this relationship was significant in cross-sectional and longitudinal studies. This review provides evidence on the transdiagnostic factors of intolerance of uncertainty, emotional dysregulation and rumination in the relationship with depression and PTSD symptoms.

Online multidisciplinary treatment of binge eating disorder in people with high weight: a case series study.

BACKGROUND: Binge eating disorder (BED) is the most frequent eating behavior among the general population (Guerdjikova in Med Clin 103:669-680, 2019). Many studies on interventions and BED treatments have been carried out in the United States and Europe, few have been reported in Latin American populations. People with this disorder not only have physical consequences of it but also social and psychological ones, therefore a multidisciplinary treatment approach is a good option to treat this condition. OBJECTIVE: To evaluate the feasibility of a multidisciplinary online intervention (i.e., psychological, nutritional, and physical activity) in patients with BED. METHOD: The design was a case series study of two clinical treatment groups, with pre-test and post-test psychometric measures along with two follow-ups (at 2 and 6 months). Fifteen people diagnosed with BED (2 men and 13 women), with a mean age of 34.93 years (SD=11.91) and a mean initial BMI of 42, participated in this study. The treatment was carried out over the span of 28 sessions, each one being two hours per week consisting of 1 hour of group therapy and 1 hour of individual therapy. There were four evaluations: pre, post and two follow-ups. RESULTS: Five patients did not complete the treatment (30%). The comparisons were made through the non-parametric Friedman test, finding a statistically significant decrease in binge eating symptoms (x2=15.57; p=.001), anxiety symptoms (x2=15.96; p=.001) and depression (x2=15.03; p=.002). There was an improvement in clarity (x2=11.60; p=.010) and emotional regulation (x2=7.75; p=.050), only in women. The patients reduced their body weight, and improved their eating and exercise habits by introducing fruits and vegetables and including 20-30 minutes of physical activity into their daily routine. Regarding the Objective Clinical Change Index, in terms of the objective clinical change, a positive change was observed in all the variables addressed. CONCLUSIONS: The data presented allowed us to conclude that the online multidisciplinary intervention was effective in the treatment of BED. Trial registration Retrospectively registered.

Genetic Ancestry, Race, and Severity of Acutely Decompensated Cirrhosis in Latin America.

BACKGROUND & AIMS: Genetic ancestry or racial differences in health outcomes exist in diseases associated with systemic inflammation (eg, COVID-19). This study aimed to investigate the association of genetic ancestry and race with acute-on-chronic liver failure (ACLF), which is characterized by acute systemic inflammation, multi-organ failure, and high risk of short-term death. METHODS: This prospective cohort study analyzed a comprehensive set of data, including genetic ancestry and race among several others, in 1274 patients with acutely decompensated cirrhosis who were nonelectively admitted to 44 hospitals from 7 Latin American countries. RESULTS: Three hundred ninety-five patients (31.0%) had ACLF of any grade at enrollment. Patients with ACLF had a higher median percentage of Native American genetic ancestry and lower median percentage of European ancestry than patients without ACLF (22.6% vs 12.9% and 53.4% vs 59.6%, respectively). The median percentage of African genetic ancestry was low among patients with ACLF and among those without ACLF. In terms of race, a higher percentage of patients with ACLF than patients without ACLF were Native American and a lower percentage of patients with ACLF than patients without ACLF were European American or African American. In multivariable analyses that adjusted for differences in sociodemographic and clinical characteristics, the odds ratio for ACLF at enrollment was 1.08 (95% CI, 1.03-1.13) with Native American genetic ancestry and 2.57 (95% CI, 1.84-3.58) for Native American race vs European American race CONCLUSIONS: In a large cohort of Latin American patients with acutely decompensated cirrhosis, increasing percentages of Native American ancestry and Native American race were factors independently associated with ACLF at enrollment.

El consumo de bebidas dulces incrementa diferencialmente la expresión de Oxitocina en núcleos hipotalámicos / The consumption of sweet drinks differentially increases the expression of oxytocin in hypothalamic nuclei

Resumen Se reconoce la participación de la oxitocina en el control de la alimentación, pero su mecanismo de acción no se ha establecido totalmente. Por tanto, el objetivo de esta investigación fue evaluar el efecto del acceso intermitente a una solución de sacarosa, sobre la expresión de las neuronas del núcleo paraventricular (PVN) y del núcleo supraótico (SON) que producen oxitocina (Oxt), y caracterizar la microestructura de la conducta de beber en ratas saciadas. Se tuvieron tres grupos de ratas macho Wistar saciadas, y en la primera hora al inicio del periodo de luz, el grupo Control tuvo agua, el grupo Restringido 5g de una solución de sacarosa al 20% y el grupo Ad libitum acceso libre a la solución de sacarosa. Los sujetos incrementaron el consumo de la solución de sacarosa a pesar de estar saciados; debido a la interrupción del estado de saciedad y la demora de la satisfacción. La actividad de las neuronas de Oxt se incrementó en ambos núcleos, en el grupo Restringido la mayor expresión se observó en el SON y en el grupo Ad libitum en el PVN. No se encontró correlación entre la cantidad de bebida ingerida y la actividad de las neuronas Oxt.

Abstract The role of oxytocin in feeding control is recognized, but its mechanism of action has not been fully established. Therefore, the aim of this research was to evaluate the effect of intermittent access to a sucrose solution on the expression of paraventricular nucleus (PVN) and supraotic nucleus (SON) neurons that produce oxytocin (Oxt), and to characterize the microstructure of drinking behavior in satiated rats. Three groups of male Wistar rats satiated were used, and in the first hour at the beginning of the light period, a Control group had water, a Restricted group 5g of a 20% sucrose solution and Ad libitum group with free access to sucrose solution. The experimental subjects increased the consumption of the sucrose solution despite being satiated, due to the interruption of the state of satiety and the delay of the satiation process. Oxt neurons increased their activity in both nuclei, in the Restricted group the highest expression was observed in the SON and in the Ad libitum group in the PVN. No correlation was found between the amount of drink ingested and the activity of Oxt neurons.

Avoidant/restrictive food intake disorder (ARFID): systematic review of case studies / Trastorno de evitación/restricción de la ingesta de alimentos (TERIA): revisión sistemática de estudios de caso

Abstract Avoidant/restrictive food intake disorder (ARFID) has a complex clinical presentation. Since its recognition in the DSM-5, investigations have provided data of this condition, however, its treatment has mostly been reported in case studies. Therefore, the objective of the present study was analyzed clinical characteristics and clinical interventions reported in case reports and case series studies of ARFID, from a literature review according to the PRISMA and CARE guidelines. In total, 41 articles were examined, most of the reported cases were males (53.85%) with ages between 10 to 13 (29.23%), although, 15.38% of the cases had an age range of 20 to 56. Regarding their symptoms, the most frequent was underweight (66.15%), however, 3.08% of these patients were overweight linked to carbohydrate consumption. The most frequent psychiatric comorbidities were anxiety disorders (38.46%). Lastly, the most widely used was hospital treatment (46.34%), with a multidisciplinary approach (65.85%) and as for the most used psychological intervention was Cognitive Behavioral Therapy (21.95%).

Resumen El Trastorno de evitación/restricción de la ingesta de alimentos (TERIA) tiene una presentación clínica compleja. Desde su reconocimiento en el DSM-5 se han realizado investigaciones que aportan datos de esta condición, sin embargo, su tratamiento se ha reportado mayormente en estudios de casos. Por tanto, el objetivo del presente estudio fue analizar las características e intervenciones clínicas de estudios y series de casos del TERIA, a partir de una revisión de la literatura con base a los lineamientos PRISMA y CARE. En total se examinaron 41 artículos, la mayoría de los casos reportados fueron en hombres (53.85%) con edades entre 10 a 13 (29.23%), aunque, 15.38% de los casos tenían un rango de edad de 20 a 56 años. En cuanto a sus síntomas, el más frecuente fue el bajo peso (66.15%), sin embargo, 3.08% de estos pacientes presentaba sobrepeso ligado al consumo de carbohidratos.

Sympathetic nervous activation, mitochondrial dysfunction and outcome in acutely decompensated cirrhosis: the metabolomic prognostic models (CLIF-C MET).

BACKGROUND AND AIMS: Current prognostic scores of patients with acutely decompensated cirrhosis (AD), particularly those with acute-on-chronic liver failure (ACLF), underestimate the risk of mortality. This is probably because systemic inflammation (SI), the major driver of AD/ACLF, is not reflected in the scores. SI induces metabolic changes, which impair delivery of the necessary energy for the immune reaction. This investigation aimed to identify metabolites associated with short-term (28-day) death and to design metabolomic prognostic models. METHODS: Two prospective multicentre large cohorts from Europe for investigating ACLF and development of ACLF, CANONIC (discovery, n=831) and PREDICT (validation, n=851), were explored by untargeted serum metabolomics to identify and validate metabolites which could allow improved prognostic modelling. RESULTS: Three prognostic metabolites strongly associated with death were selected to build the models. 4-Hydroxy-3-methoxyphenylglycol sulfate is a norepinephrine derivative, which may be derived from the brainstem response to SI. Additionally, galacturonic acid and hexanoylcarnitine are associated with mitochondrial dysfunction. Model 1 included only these three prognostic metabolites and age. Model 2 was built around 4-hydroxy-3-methoxyphenylglycol sulfate, hexanoylcarnitine, bilirubin, international normalised ratio (INR) and age. In the discovery cohort, both models were more accurate in predicting death within 7, 14 and 28 days after admission compared with MELDNa score (C-index: 0.9267, 0.9002 and 0.8424, and 0.9369, 0.9206 and 0.8529, with model 1 and model 2, respectively). Similar results were found in the validation cohort (C-index: 0.940, 0.834 and 0.791, and 0.947, 0.857 and 0.810, with model 1 and model 2, respectively). Also, in ACLF, model 1 and model 2 outperformed MELDNa 7, 14 and 28 days after admission for prediction of mortality. CONCLUSIONS: Models including metabolites (CLIF-C MET) reflecting SI, mitochondrial dysfunction and sympathetic system activation are better predictors of short-term mortality than scores based only on organ dysfunction (eg, MELDNa), especially in patients with ACLF.

Suicide risk model based on the interpersonal theory of suicide: evidence in three regions of Mexico / Modelo de riesgo suicida basado en la teoría interpersonal del suicidio: evidencia en tres regiones de México

Background: Reports of suicidal behavior have increased in Mexico for years. In order to develop a more adequate suicide prevention strategy, it is necessary to understand its predictive factors, so the purpose of this research was to propose a model of suicidal risk in young people, taking into account one of the most current theories on the subject, Joiner's interpersonal theory. Method: A non-probabilistic sample of young people with suicidal ideation from three regions of Mexico was obtained by online survey (N=411), with mean age of 17.89 years (SD. 1.2), 336 women (81.8%), and 75 men (18.2%). Results: First, a multiple linear regression model was created to predict suicidal risk based on thwarted belongingness and perceived burden with 17% explained variance; then a second model was generated with the same variables and including other factors associated with suicide such as self-injury desires, impulsivity and suicide attempts, in addition to variables associated with family conflicts, improving the explained variance to 34%. Lastly, two properly adjusted structural equation models were obtained, one focused on suicidal risk (R2=.21; RMSEA=.026; CFI=.99) and the other on ideation (R2=.18; RMSEA=.070; CFI=.98). Conclusions: The main factors that explain suicidal risk are depressive symptoms, perceived burden and desires for self-injury. Further research on the effect of painful experiences as factors that could predict suicide attempt is suggested.

Introducción: Los reportes de conducta suicida en México han aumentado por años. Para desarrollar una estrategia más adecuada de prevención del suicidio es necesario comprender sus factores predictores, por lo que el propósito de la presente investigación fue proponer un modelo del riesgo suicida en jóvenes tomando en cuenta una de las teorías más vigentes en cuanto al tema, la teoría interpersonal de Joiner. Método: Se obtuvo por encuesta online una muestra no probabilística de jóvenes con ideación suicida de tres regiones de México (N=411), con una edad media de 17.89 años (DE. 1.2), 336 mujeres (81.8%) y 75 hombres (18.2%). Resultados: Primero se conformó un modelo de regresión lineal múltiple para predecir riesgo suicida a partir del sentido de pertenencia frustrado y la carga percibida con 17% de varianza explicada; después se generó un segundo modelo con las mismas variables e incluyendo otros factores asociados al suicidio como los deseos de autolesión, impulsividad e intentos suicidas, además de variables asociadas a conflictos familiares, mejorando la varianza explicada hasta un 34%. Por último, se obtuvieron dos modelos de ecuaciones estructurales con ajuste adecuado, uno enfocado en riesgo suicida (R2=.21; RMSEA=.026; CFI=.99) y otro en la ideación (R2=.18; RMSEA=.070; CFI=.98). Conclusiones: Los principales factores que explican el riesgo suicida son los síntomas depresivos, la carga percibida y los deseos de autolesión, se sugiere seguir investigando sobre el efecto de experiencias dolorosas como factores que podrían predecir el intento suicida.

Cross-cultural adaptation and validation of the Nine Item ARFID Screen (NIAS) in Mexican youths.

Avoidant/Restrictive Food Intake Disorder (ARFID) is defined by limited volume or variety of food intake motivated by the sensory properties of food, fear of aversive consequences, or lack of interest in food or eating associated with medical, nutritional, and psychosocial impairment. Currently, two of the most widely validated measures are The Eating Disturbances in Youth-Questionnaire (EDY-Q) and the Nine Item ARFID Screen (NIAS). The latter has proven valid and reliable for assessing this disorder. OBJECTIVE: To validate a culturally sensitive adaptation of the NIAS instrument and evaluate its psychometric properties in Mexican youths. METHOD: The sample consisted of 800 participants aged 12-30 (M = 18.56, SD = 3.52) from Mexico City and Hidalgo public educational institutions. RESULTS: The S-NIAS obtained a Cronbach's alpha of 0.84, adequate construct validity adjustment rates: CMIN = 1.88; GFI = 0.97; AGFI = 0.94; CFI = 0.98; RMR = 0.050; and RMSEA = 0.047. Measurement invariance by gender, age, and survey administration which show that construct is understood in the same way across both groups and despite the change from paper-and-pencil to online survey administration. CONCLUSION: The psychometric properties of the Spanish Nine Item ARFID Screen (S-NIAS) indicate that it is a valid and reliable instrument for evaluating symptoms associated with ARFID in this sample of youths. PUBLIC SIGNIFICANCE: Although there are advances in studying ARFID, their epidemiological data comes mainly from a few countries. Furthermore, these data are scarcer due to the lack of validated screening and assessment instruments available in a variety of world languages; having instruments for the evaluation of ARFID symptoms is essential because it could function as an auxiliary means for the detection and prevention of people at risk.

Post-transplant diabetes mellitus and renal cell cancer after renal transplantation.

BACKGROUND: Diabetes is a risk factor for cancer in the general population. However, few data are available on the association between post-transplant diabetes mellitus (PTDM) and cancer after transplantation. METHODS: We analyzed this issue in a Spanish cohort of patients without diabetes before transplantation. PTDM was diagnosed with consensus criteria at 12 months after transplantation and 12 months before the diagnosis of cancer. The association between PTDM and cancer (overall and specific types) was evaluated with regression analysis. RESULTS: During a follow-up of 12 years (interquartile range 8-14), 85 cases of 603 developed cancer (829/100 000/year) and 164 (27%) PTDM. The most frequent cancers were renal cell cancer (RCC) n = 15, 146/cases/100 000/year), lung (n = 12, 117/cases/100 000/year), colon (n = 9, 88/cases/100 000/year) and prostate (n = 9, 88/cases/100 000/year). In logistic regression, PTDM was not associated with cancer. Eight of the 164 patients with PTDM (4.9%) vs 7 of the 439 without PTDM developed RCC (1.6%) (P = .027). In multivariate analysis, PTDM was independently associated with RCC [odds ratio (OR) 2.92, confidence interval (CI) 1.03-8.27], adjusting for smoking (OR 4.020, 95% CI 1.34-12.02) and other covariates. PTDM was not associated with other types of cancer. CONCLUSIONS: Patients with PTDM must be considered a population at risk for RCC and accordingly, the subject of active surveillance.

Composición corporal, presencia de anorexia nerviosa y sintomatología asociada en bailarines de danza folclórica / Body composition, presence of anorexia nervosa and associated symptoms in folkloric dancers

Resumen Dada la exigencia en la disciplina dancística sobre los requerimientos corporales del bailarín, se han llevado a cabo diversos estudios sobre trastornos alimentarios (TA), sin embargo, son escasos los datos en bailarines de danza folklórica. Por tal motivo, el objetivo del presente trabajo fue conocer la composición corporal, imagen corporal, sintomatología y presencia de anorexia nerviosa en bailarines de danza folklórica profesionales (n = 37), recreativos (n = 37) y en muestra comunitaria (n = 37). El estudio se llevó a cabo en dos fases, en la primera se aplicaron los instrumentos EAT-26 y BSQ, además, se calculó el porcentaje de grasa corporal (PGC), el índice de masa corporal (IMC) y la masa muscular esquelética (MME). En la segunda fase se entrevistaron a aquellos que rebasaron punto de corte del EAT-26 y/o BSQ así como a un grupo control de la misma muestra que no haya rebasado ningún punto de corte para descartar falsos negativos. Solo se encontraron diferencias entre grupos en IMC y en PGC. De acuerdo con las entrevistas, ningún participante fue diagnosticado con anorexia nerviosa pero sí con sintomatología de TA. Se concluye que los estándares corporales exigidos en danza folklórica, son lo suficientemente altos como para que los bailarines realicen conductas de riesgo que podrían comprometer su salud física y psicológica.

Abstract Given the strict discipline in dancing activities and on the body requirements, wide research has been performed on eating disorders (ED) in this field, however, data on folk dancers are scarce. For this reason, the aim of this study was to know the body composition, body image, symptomatology and presence of anorexia nervosa in professional folkloric dancers (n = 37), recreational dancers (n = 37) and in a community sample (n = 37). The study was carried out in two phases, in the first one, the EAT-26 and BSQ instruments were administered, in addition, the body fat percentage (BFP), the body mass index (BMI) and the skeletal muscle mass (SMM) were obtained. In the second phase, those who exceeded the cut-off point of EAT-26 and/or BSQ were interviewed, as well as a control group of the same sample that did not scored above the cut-off point of any instrument to detect false negatives. Differences were only found between groups in BMI and BFP. According to the interviews, no participant was diagnosed with anorexia nervosa, but they were diagnosed with ED symptoms. It is concluded that the body standards required in folk dance are high enough for dancers to perform risky behaviors that could compromise their physical and psychological health.

Pseudohypoparathyroidism: an endocrine orphan disease. case report

Introduction: Pseudohypoparathyroidism (PHP) is a heterogeneous group of rare endocrine disorders characterized by resistance to the parathyroid hormone. There are few reports on PHP in Colombia, so the publication of the present case contributes to increase the interest in its research in the clinical setting. Case presentation: An 18-year-old male with a history of hypothyroidism diagnosed at 4 months of age, stunted growth, delayed puberty, obesity, brachydactyly, pathologic fractures, femoral osteochondroma, insomnia, paresthesia, and chronic constipation was referred to the endocrinology service of a tertiary care center in Bogotá (Colombia) after being hospitalized following a seizure episode. On admission, laboratory tests revealed hypocalcemia, hyperphosphatemia, 25-hydroxy vitamin D in the range of insufficiency and elevated PTH. Imaging studies showed heterotopic ossifications and calcifications of the basal ganglia. A genetic study confirmed the diagnosis of PHP1A, so treatment was started with calcium, cholecalciferol and phosphorus chelators, leading to a satisfactory course. Both the patient and his first-degree relatives received genetic counseling and interdisciplinary assessment. Conclusion: Although PHP type 1A is an unrecognized complex genetic disorder, it has a critical clinical importance within the differential diagnoses of hypocalcemia. Without prompt diagnosis and treatment, patients may experience serious and potentially fatal metabolic consequences.

Introducción. El seudohipoparatiroidismo (SPT) es un trastorno genético poco frecuente que se caracteriza por la resistencia a la hormona paratiroidea (PTH). En Colombia existen pocos reportes sobre esta enfermedad, por lo que la publicación del presente caso contribuye a aumentar el interés en su búsqueda en el ámbito clínico. Presentación del caso. Hombre de 18 años con antecedente de hipotiroidismo (diagnosticado a los 4 meses de nacido), retraso del crecimiento, desarrollo puberal tardío, obesidad, braquidactilia, fracturas patológicas, osteocondroma femoral, insomnio, parestesias y estreñimiento crónico, quien asistió al servicio de endocrinología de un hospital de tercer nivel de Bogotá (Colombia) remitido luego de haber estado hospitalizado por un episodio convulsivo. En dicha hospitalización los laboratorios evidenciaron hipocalcemia, hiperfosfatemia y 25-OH vitamina D en rango de insuficiencia con niveles elevados de PTH, y los estudios imagenológicos demostraron osificaciones heterotópicas y calcificaciones de ganglios basales del cerebro. Al paciente se le realizó un estudio genético que confirmó el diagnóstico de SPT1A, por lo que se le inició manejo con suplencia de calcio, colecalciferol y quelantes de fósforo, con lo cual evolucionó satisfactoriamente. Tanto el paciente como sus familiares de primer grado recibieron asesoramiento y valoración interdisciplinaria. Conclusiones. El SPT1A es un trastorno genético complejo poco conocido pero de alta importancia clínica dentro de los diagnósticos diferenciales de hipocalcemia que debe considerarse ya que sin el diagnóstico y tratamiento oportunos, los pacientes pueden presentar consecuencias metabólicas graves y potencialmente fatales.

A Physiotherapy Treatment Plan for Post-COVID-19 Patients That Improves the FEV1, FVC, and 6-Min Walk Values, and Reduces the Sequelae in 12 Sessions.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causal agent of Coronavirus disease 2019 (COVID-19), a pandemic disease declared in 2020. The clinical manifestations of this pathology are heterogeneous including fever, cough, dyspnea, anosmia, headache, fatigue, taste dysfunction, among others. Survivors of COVID-19 have demonstrated several persistent symptoms derived from its multisystemic physiopathology. These symptoms can be fatigue, dyspnea, chest pain, dry and productive cough, respiratory insufficiency, and psychoemotional disturbance. To reduce and recover from the post-COVID-19 sequelae is fundamental an early and multifactorial medical treatment. Integral post-COVID-19 physiotherapy is a tool to reduce dyspnea, improve lung capacity, decrease psychoemotional alterations, as well as increase the muscle strength affected by this disease. Thus, the aim of this study was to establish a novel physiotherapeutic plan for post-COVID-19 patients, evaluating the effect of this treatment in the reduction of the sequelae in terms of lung capacity, cardio-respiratory, and muscular strength improvements. This was a cross-sectional study in which a protocol of 12 sessions in 4 weeks of physiotherapy was implemented in the patients enrolled. We conducted a medical assessment, an interview, a DASS-21 test, a spirometry, a 6-min walk test, and a hand dynamometer test to evaluate the post-COVID condition of patients before and after the sessions. A total of 42 patients participated in the program. Results of this work showed a decrease of around 50% of post-COVID-19 sequelae and an improvement in the psychoemotional status of patients. Also, we observed an increase of 7.16% in the FEV1 value and 7.56% for FVC. In addition, the maximal functional capacity increased by 0.577 METs, the 6-min walk test performance increased by 13%, and the SpO2 improved by 1.40%. Finally, the handgrip strength test showed an improvement in the left hand and right hand of 2.90 and 2.24 Kg, respectively. We developed this study to propose a novel methodology to provide information for a better treatment and management of post-COVID-19 patients.

Characterization of Candida albicans and Staphylococcus aureus polymicrobial biofilm on different surfaces.

BACKGROUND: Staphylococcus aureus and Candida albicans have been co-isolated from biofilm-associated diseases such as denture stomatitis, periodontitis, and burn wound infections, as well as from medical devices. However, the polymicrobial biofilm of both microorganisms has not been fully characterized. AIMS: To characterize the polymicrobial biofilm of C. albicans and S. aureus in terms of microbial density, synergy, composition, structure, and stability against antimicrobials and chemical agents. METHODS: Crystal violet assay was used to measure the biofilm formation. Scanning electron microscopy and confocal microscopy were used to analyze the structure and chemical composition of the biofilms, respectively. RESULTS: Supplemented media with fetal bovine serum (FBS) decreased the biofilm formation of S. aureus and the polymicrobial biofilm. For C. albicans, depending on the culture media, the addition of glucose or FBS had a positive effect in biofilm formation. FBS decreased the adhesion to polystyrene wells for both microorganisms. Supplementing the media with glucose and FBS enhanced the growth of C. albicans and S. aureus, respectively. It seems that C. albicans contributes the most to the adhesion process and to the general structure of the biofilms on all the surfaces tested, including a catheter model. Interestingly, S. aureus showed a great adhesion capacity to the surface of C. albicans in the biofilms. Proteins and ß-1,6-linked polysaccharides seem to be the most important molecules in the polymicrobial biofilm. CONCLUSIONS: The polymicrobial biofilm had a complex structure, with C. albicans serving as a scaffold where S. aureus adheres, preferentially to the hyphal form of the fungus. Detection of polymicrobial infections and characterization of biofilms will be necessary in the future to provide a better treatment.
