Cross-cultural adaptation, reliability and validity of the Spanish version of the long-term quality of life questionnaire.

Purpose: The aim of this study was to translate, culturally adapt, and evaluate the psychometric properties of the Spanish Long-Term Quality of Life (LTQL) questionnaire. Methods: The LTQL was initially translated into Spanish and cross-culturally adapted based on established guidelines. The Spanish LTQL was administered to patients with breast cancer who had completed their initial treatment 5 years earlier, along with other self-report measures: Quality of Life in Adult Cancer Survivors (QLACS), Hospital Anxiety and Depression Scale (HADS) and EORT-QLQ-BR23. Reliability was evaluated using internal consistency and test-retest. Convergent and known-groups validity were examined. Structural validity as determined by confirmatory factor analysis (CFA) and Rasch analyses was used to assess the unidimensionality and item-functioning of the LTQL domains. Results: Cronbach's alpha were above 0.7 in all domains. Test-retest coefficients were between 0.72 to 0.96 for LTQL domains. LTQL total score was correlated with others total scores of other measures: QLACS (r=-0.39), HADS depression (r=-0.57), HADS anxiety (-0.45) and EORTC-QLQ-BR23 (r=-0.50). CFA provided satisfactory fit indices, with RMSEA value of 0.077 and TLI and CFI values of 0.901 and 0.909, respectively. All factor loadings were higher than 0.40 and statistically significant (P<0.001). Rasch analysis showed that Somatic Concerns domain had 4 misfitting items, and Philosophical/Spiritual View of Life and social Support domains only 1 misfit item. However, unidimensionality was supported for the four domains. Conclusion: The findings support the validity and reliability of the Spanish version of LTQL questionnaire to be used in long-term cancer female survivors.

Characteristics Associated With Elevated Time Below Range in Elderly Patients With Type 1 Diabetes Using an Automated Insulin Delivery System.

BACKGROUND: This study investigated the characteristics associated with an increased risk of hypoglycemia, in elderly patients with type 1 diabetes mellitus (T1D) using automated insulin delivery (AID) systems. METHODS: Cross-sectional observational study including patients >60 years, using sensor-augmented insulin pump therapy with predictive low-glucose management (SAPT-PLGM), hybrid closed-loop (HCL), and advanced hybrid closed-loop (AHCL), for more than three months. A geriatric assessment was performed, and body composition was determined to investigate its association with achieving time below range (TBR) <70 mg/dL goals. RESULTS: The study included 59 patients (47.5% of men, mean age of 67.6 years, glycated hemoglobin [HbA1c] of 7.5 ± 0.6%, time in range (TIR) 77.8 ± 9.9%). Time below range <70 and <54 mg/dL were 2.2 ± 2.3% and 0.4 ± 0.81%, respectively. Patients with elevated TBR <70 mg/dL (>1%) had higher HbA1c levels, lower TIR, elevated time above range (TAR), and high glycemic variability. Regarding body composition, greater muscle mass, grip strength, and visceral fat were associated with a lower TBR <70 mg/dL. These factors were independent of the type of technology used, but TIR was higher when using AHCL systems compared with SAPT-PLGM and HCL systems. CONCLUSIONS: In elderly patients treated with AID systems with good functional status, lower lean mass, lower grip strength, and lower visceral fat percentage were associated with TBR greater than 1%, regardless of the device used. A similar finding along was found with CGM indicators such as higher HbA1c levels, lower TIR, higher TAR, and higher CV. Geriatric assessment is crucial for personalizing patient management.

Results From a Virtual Clinic for the Follow-up of Patients Using the Advanced Hybrid Closed-Loop System.

BACKGROUND: Evidence regarding the implementation of medium-term strategies in advanced hybrid closed-loop (AHCL) system users is limited. Therefore, this study aimed to describe the efficacy and safety of the AHCL system in patients with type 1 diabetes (T1D) on a six-month follow-up in a virtual diabetes clinic (VDC). METHOD: A prospective cohort of adult patients with T1D treated using the AHCL system (Mini Med 780G; Medtronic, Northridge, California) in a VDC follow-up. Standardized training and follow-up were conducted virtually. Clinical data and metabolic control outcomes were reported at baseline, and at three and six months. RESULTS: Sixty-four patients (mean age = 42 ± 14.6 years, 65% men, 54% with graduate education) were included. Percentage time in range (%TIR) increased significantly regardless of prior therapy with intermittently scanned continuous glucose monitoring + multiple daily injections and sensor-augmented pump therapy with predictive low-glucose management after starting AHCL and persisted during the follow-up period with no hypoglycemic events. The %TIR 70 to 180 mg/dL according to socioeconomic strata was 73.4% ± 5.3%, 78.1% ± 8.1%, and 84.2% ± 7.5% for the lower, middle, and upper strata, respectively. The sensor was used more frequently in the population with a higher education level. Adherence to sensor use and SmartGuard retention were higher in patients who underwent the VDC follow-up. CONCLUSIONS: Medium-term follow-up of users of AHCL systems in a VDC contributes to safely achieving %TIR goals. Virtual diabetes clinic follow-up favored adherence to sensor use and continuous SmartGuard use. Socioeconomic strata were associated with a better glycemic profile and education level was associated with better adherence to sensor use.

Impact of hospitalization on nutritional status in persons aged 65 years and over (NUTRIFRAG Study): Protocol for a prospective observational study.

BACKGROUND: Malnutrition is a recurring problem that has become more relevant in recent years. The aim of this study is to assess the risk of malnutrition and nutritional status on admission and its evolution until discharge in patients aged 65 and over admitted to medical and surgical hospitalization units in hospitals of the Spanish National Health System. METHODS: Prospective observational study to be carried out in the medical-surgical hospitalization units of 9 public hospitals between 01/09/2022 and 31/12/2024. Using consecutive sampling, a total of 4077 patients will be included (453 in each hospital). Variables included are related to the care process, functionality, cognition and comorbidity, risk profile, nutritional status and dysphagia; as well as frailty, dietary quality and contextual variables. The incidence of risk of malnutrition, undernutrition and dysphagia during the care process and at discharge will be calculated. The association with risk factors will be studied with logistic regression models and multivariate Cox regression models. In addition, an analysis of participants' satisfaction with food services will be carried out. The study was approved by the Ethics and Research Committee on 30/09/2020, approved for funding on 02/12/2021 and with registration number RBR-5jnbyhk in the Brazilian clinical trials database (ReBEC) for observational studies. DISCUSSION: Some studies address nutritional status or dysphagia in older people in various care settings. However, there is a lack of large sample studies including both processes of the impact of hospitalization. The results of the project will provide information on the incidence and prevalence of both pathologies in the study subjects, their associated factors and their relationship with the average length of stay, mortality and early readmission. In addition, early detection of a problem such as malnutrition related to the disease and/or dysphagia during a hospital stay will favor the action of professionals to resolve both pathologies and improve the health status of patients.

Glycemic control metrics in a cohort of hospitalized patients with type 1 diabetes using hybrid closed-loop and advanced hybrid closed-loop systems.

AIMS: To describe Hybrid closed-loop (HCL) and advanced hybrid closed-loop (AHCL) performance in the hospital setting based on the continuous glucose monitoring (CGM) metrics description. METHODS: This was an observational study from a cohort of patients with T1D using HCL/AHCL with history of hospitalization. CGM metrics were analyzed during the hospital stay. CGM metrics sub-analysis of the population with active Automated Mode (AM) and SmartGuard (SG) during hospitalization and/or surgical procedure was performed. RESULTS: Twenty-four patients were included (50 % women; mean age, 49 years [inter-quartile range (IQR), 39-62 years]). During hospitalization 70.8 % patients achieved %Time in Range (TIR) between 70 and 180 mg/dL ≥ 70 %. The overall %TIR was 75.5 % (IQR, 67.3-81.5 %), % time below range (TBR) < 70 mg/dL was 2.1 % (IQR, 0.7-5.4 %) and %TBR < 54 mg/dL was 0 % (IQR, 0-5.4 %). Users of the AHCL with active SG achieved a non-significant higher %TIR during hospitalization (79 % [73.8.88 %] vs. 76 % [72.81 %], p = 0.312) and had a shorter stay (3[IQR, 2.4] vs. 6 days[IQR, 5.7], p = 0.045) compared to the users of the HCL with AM active. No device-related serious adverse events occurred for users of either system. CONCLUSIONS: HCL/AHCL systems with active AM/SG in patients with T1D in the hospital environment leads to %TIR > 70 % in ranges of 70-180 mg/dL in patients without increasing hypoglycemia.

Numerical and clinical precision in hypoglycemia of the intermittent FreeStyle Libre glucose monitoring through an NFC-Bluetooth transmitter associated with the xDrip+ algorithm in diabetic patients under insulin therapy.

INTRODUCTION: There are data capture devices that attach to the FreeStyle Libre sensor and convert its communication from NFC (Near-field communication) to Bluetooth technology, generating real-time continuous glucose monitoring. The accuracy of hypoglycemia measurements displayed by smartphone apps using this device has not been established. METHODS: Study of diagnostic tests. Numerical accuracy was evaluated, utilizing the absolute difference with respect to capillary glucometry (ISO 15197:2015 standard) and clinical accuracy, using the Clarke and Parkes (Consensus) error grids, for glucose measurements less than 70mg/dL performed with the FreeStyle Libre system and with the digital estimation xDrip+ app, in diabetic patients managed with insulin therapy. RESULTS: Twenty-seven patients were included (TIR 73.4%, TBR70 5.6%), who contributed 83 hypoglycemic events. Numerical accuracy was adequate in similar proportions with the FreeStyle Libre system compared to the xDrip+ app (81.92% vs. 68.67%, p=0.0630). The clinical accuracy evaluation showed that 92.8% of the measurements for xDrip+ and 98.8% for FreeStyle libre met the criteria according to the Parkes (Consensus) grid (p=0.0535); and 79.5% and 91.6% of the measurements met the criteria according to the Clarke grid (p=0.0273), being higher with FreeStyle libre. CONCLUSIONS: The use of the NFC-Bluetooth transmitter (Miao-Miao) associated with the xDrip+ app does not improve numerical or clinical accuracy for detecting hypoglycemic events in diabetic patients managed with insulin therapy, compared to the FreeStyle Libre device.

Prognostic Significance of p53 and p63 in Diffuse Large B-Cell Lymphoma: A Single-Institution Experience.

Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma in adults. We evaluated the immunohistochemical (IHC) expression of p63 and p53 in DLBCL and their significance on overall survival (OS) and progression-free survival (PFS). We conducted a retrospective cohort study of 177 patients with DLBCL who presented to Mount Sinai Medical Center of Florida (Miami Beach, Florida) between 2010 and 2020. IHC staining for p63 and p53 protein expression was performed. A significant correlation was found between p63 positivity and p53 expression, p53/p63 co-positivity, Ki-67 proliferation index, MYC expression, and MYC/BCL2 double expression. Regardless of the germinal center B-cell like (GCB) subgrouping, there was a trend among p53+ patients to have MYC/BCL2 double expression, positive MYC expression, and lower OS and PFS. A tendency of poor OS was seen in p53+ patients in the non-GCB, GCB, and double expressors subgroups and poor PFS in p53+ patients regardless of the subgrouping. In conclusion, our results suggest that p63 and p53 may represent potential additional prognostic biomarkers in DLBCL and may be included in the initial diagnostic work up of patients with DLBCL.

Novel ATM Gene c.5644 C > T (p.Arg1882*) Variant Detected in a Patient with Pancreatic Adenocarcinoma and Two Primary Non-Small Cell Lung Adenocarcinomas: A Case Report

Ataxia-telangiectasia is an autosomal recessive disorder that usually manifests in childhood due to mutations in the Ataxia-Telangiectasia Mutated (ATM) gene. It is believed that there is an association between this gene mutation/polymorphism and cancer risk, including breast, lung, and pancreatic cancers. We report a rare case of a 69-year-old woman who developed three different primary cancers, including non-small cell lung cancer (NSCLC) in both lungs and pancreatic adenocarcinoma, and was later found to have a rarely reported variant mutation in the ATM gene, namely Exon 39, c.5644 C > T. We hypothesize that the ATM gene, c.5644 C > T mutation could be a plausible contributor in the pathogenesis of these three cancers. This hypothesis has yet to be validated by larger studies that focus on a mechanistic approach involving DNA repair genes such as the ATM. More importantly, this paves the way to developing new patient-specific targeted therapies and inaugurating precision medicine as a cornerstone in cancer therapeutics.

Information needs and research priorities in long-term survivorship of breast cancer: Patients and health professionals' perspectives.

OBJECTIVE: The objective of this work is to identify unmet information needs of long-term-survivors of breast cancer (BC) and future research needs from the perspectives of patients and health care professionals. METHODS: Two online Delphi surveys were conducted. Participants in Survey 1 were patients. Participants in Survey 2 were health care professionals from both primary and secondary care involved in BC care. Both surveys included three successive rounds. The first round aimed to identify research and information needs; the second round aimed to rank the relative importance of those needs; the third round aimed to find consensus. RESULTS: The most important information needs were self-management recommendations of common health problems after treatment and complications of breast reconstruction after 5 years. The most important research priorities were related to interventions and tools to increase information provision by professionals about certain tests, diet, and coordinated action between primary and specialised care during follow-up, and indications and safety issues of pregnancy in survivors. CONCLUSIONS: Two fundamental ideas were identified: (1) Patients request information about self-management common health problems after treatment and breast reconstruction complications. (2) Health care professionals emphasise the need for a standardised approach based on protocols, recommendations, and coordinated actions in the provision of information. IMPLICATIONS FOR CANCER SURVIVORS: Given the increasing number of BC survivors, it is essential to identify information and research needs to improve their care and health outcomes.

Effectiveness and safety of new oral and injectable agents for in-hospital management of type 2 diabetes in general wards: Systematic review and meta-analysis.

BACKGROUND: Current guidelines recommend insulin alone for in-hospital management of diabetes, but growing information suggests that new oral or injectable agents may be as effective and safe. METHODS: Systematic review and meta-analysis with evidence from randomized (RCT) and non-randomized (NRS) studies in PubMed, EMBASE and LILACS databases up to February 10, 2022, for studies including hospitalized type 2 diabetes patients, comparing dipeptidyl peptidase 4 inhibitors (DPP4i), sodium glucose co-transporter 2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonist (GLP1Ra) with insulin alone for glycemic control and safety outcomes. FINDINGS: 7 RCT and 3 NRTs were included. There were no differences in mean blood glucose, measurements within range or rate of hypoglycemia between DPP4i and insulin. We found a lower mean glucose for GLP1Ra plus insulin subgroup (-16.36 mg/dL, 95 % CI -27.31, -5.41; I2 = 0 %) with lower incidence of hypoglycemia < 70 mg/dL with GLP1Ra (RR 0.31, CI 95 % 0.14-0.70, I2 = 0 %). SGLT2i data was limited. Adverse events rates were similar between treatments. CONCLUSION: Our review suggests that inpatient management in the general ward with DPP4i and GLP1Ra is as effective and safe as management with insulin. More randomized studies are required to support these findings before they could be recommended as usual practice.

Consensus for the use of flash glucose monitoring in the Colombian adult population with type 1 and 2 diabetes mellitus / Consenso para el uso de monitoreo de glucosa flash en la población adulta colombiana con diabetes mellitus tipo 1 y 2

Abstract Introduction: in Colombia, the Clinical Practice Guidelines for the treatment of patients with type 1 (DM1) and type 2 (DM2) diabetes do not mention the use of flash glucose monitoring, as this system was not available. The objective of this study was to establish a set of recommendations for the use of intermittent flash monitoring in Colombia. Methods: the group of experts consisted of eight Colombian physicians from different cities within Colombia, with expertise in the management of patients with DM1 and DM2; a certified diabetes nurse educator; a patient with DM1; and a methodological expert. Using the Zoom Enterprise video conferencing application (Zoom Video Communications, San Jose, California), the group generated questions through the Metaplan method, then carried out a systematic literature search and evidence review. The recommendations were made according to the degree of evidence and strength of the recommendation, following the GRADE method. Results: clinical recommendations were made for: a) patients with DM1 and hypoglycemia; b) patients with DM1 and poor metabolic control; c) patients with insulin-treated DM2; d) pregestational diabetes; e) quality of life; and f) inpatient use. Conclusions: this consensus's clinical recommendations guide clinical decision making with regard to the use of intermittent flash monitoring in patients with diabetes in various clinical settings.

Perfil demográfico y clínico de la poliarteritis nodosa sistémica y cutánea en un grupo de pacientes pediátricos de Medellín, 2010-2019 / Demographic and clinical profile of systemic and cutaneous Polyarteritis nodosa in a group of pediatric patients in Medellin, 2010-2019

Resumen Objetivo: describir las principales características demográficas y clínicas de los pacientes pediátricos con poliarteritis nodosa (PAN). Metodología: estudio descriptivo retrospectivo. Resultados: se obtuvieron las historias clínicas de menores de 18 años con diagnóstico de vasculitis o PAN atendidos entre el 2010 y 2019 en dos hospitales de Medellín. Se incluyeron 19 pacientes, 11 clasificados como PAN cutánea (PANC) según la definición de la Liga Europea contra el Reumatismo y la Sociedad Europea de Reumatología Pediátrica, y 8 como PAN sistémica (PANS) acorde con los criterios de Ankara 2008. El 57,9 % fueron varones (n = 11). La mediana de la edad en el diagnóstico fue 10 años (3-17 años) y del tiempo de seguimiento: 15 meses (0-105 meses). Las manifestaciones más frecuentes fueron nódulos subcutáneos (84,2 %), fiebre (57,9 %), artralgias (57,9 %) y dolor en las pantorrillas (52,6 %). Los pacientes con PANS presentaron más pérdida de peso y hemoglobina baja. 5 niños cursaron con úlceras (26,3 %) cuatro con PANC; 2 exhibieron necrosis lingual (10,5 %) y 2 necrosis digital (10,5 %), todos con PANC. El promedio de la PCR fue de 10,2 mg/dl (0,33-45,3) y, de la eritrosedimentación: 74 mm/hora (15-127 mm/hora). En las imágenes hubo un realce meníngeo, aneurismas intrahepáticas y mesentéricos, entre otros hallazgos. Todos recibieron esteroides sistémicos. Ninguno falleció. Conclusión: en esta serie, la PAN pediátrica fue más común en niños de edad escolar. La PANC fue más frecuente que la PANS. Las manifestaciones más descritas fueron los nódulos subcutáneos, las mialgias, la fiebre, las artralgias y el dolor en las pantorrillas. Aunque se ha considerado la PANC como una enfermedad benigna, estos pacientes pueden requerir tratamiento con glucocorticoides e inmunosupresores.

Summary Objective: To describe the main demographic and clinical characteristics of patients who were diagnosed with childhood polyarteritis nodosa (PAN). Methods: A descriptive study was conducted using retrospective data Results: The clinical registries from patients under 18th years with vasculitis or PAN diagnosis attended between 2010 and 2019 in two Medical Centers from Medellín were obtained. Nineteen patients were included: eleven classified as cutaneous PAN (PANC) according to the definition of the European League Against Rheumatism and the European Society of Pediatric Rheumatology and eight as systemic PAN according to Ankara 2008 Criteria. 57.9% were male. The median age at diagnosis was ten years (3-17), and the median follow-up period was 15 months (0-105). The most common clinical characteristics were subcutaneous nodules (84.2%), fever (57.9%), arthralgias (57.9%), and calf pain (52.6%). SPAN patients had more frequent weight loss and lower hemoglobin. Five patients had ulcers (26.3%), four of them with CPAN; two patients had lingual necrosis (10.5%), and two digital necrosis (10.5%), all of them also with CPAN. CRP mean was 10.2 mg/dl (0.33-45.3) and mean erythrocyte sedimentation rate (ESR) was 74 mm/h (15-127 mm/h). Meningeal enhancing, intrahepatic, and mesenteric aneurism, among others, were reported in diagnostic images. All patients required treatment with systemic glucocorticoid. None of the patients died during the follow-up period. Conclusions: In this pediatric series from Medellín-Colombia, PAN was more common in boys of school age. CPAN was more frequent than SPAN. The clinical characteristics most reported were subcutaneous nodules, myalgias, arthralgias, and calf pain. Although CPAN has been considered a benign disease, these patients may require systemic glucocorticoid and immunosuppressive therapy.

Neonicotinoids exposure assessment in Africanized honey bees (Apis mellifera L.) by using an environmentally-friendly sample preparation technique followed by UPLC-MS/MS.

A miniaturized QuEChERS extraction method followed by ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) was developed to analyze thiamethoxam and imidacloprid in 0.3 g of lyophilized Africanized honey bees (Apis mellifera L.). The work aimed to estimate honey bees' exposure to pesticides at the nanogram/gram (ng g-1) levels, using small sample and reagent quantities. Low amounts of solvents and salts were employed - 15× less than used in traditional methods. Average recoveries ranged from 64.5% to 99.7%, with repeatability below 20% for samples spiked at 3 and 167 ng g-1. LOD and LOQ were 0.7, and 3 ng g-1 for both pesticides. Applying the proposed approach, honey bee samples from different apiaries from the State of São Paulo (Brazil) were analyzed. The pesticides were detected in concentrations between 7.0 and 27.0 ng g-1. Thus, the proposed method can be used as a greener alternative to analyze the two neonicotinoids at trace levels in small quantities of bees, consequently saving chemicals and waste.

[Content validation of the spanish version of the Long-term Quality of Life Instrument for long-term female breast cancer survivors.] / Validación de contenido de la versión en castellano del instrumento Long-term Quality of Life Instrument para mujeres supervivientes de cáncer de mama de larga duración.

OBJECTIVE: The quality of life of women affected by breast cancer diagnosed 5 or more years ago has been relatively unexplored in Spain; there are no instruments for its measurement validated. The objective of the study is to translate into Spanish, culturally adapt and examine the content validity of the Spanish version of the Long-Term Quality of Life Instrument (LTQL). METHODS: The initial translation was performed by two translators with Spanish as their mother tongue carried out the translation of the questionnaire, obtaining two initial versions in Spanish (T1 and T2). An analysis of the results and elaboration of a single preliminary version in Spanish (T-1-2) were performed. The retro-translation was performed by two translators with English as their mother tongue not familiar with the original version translated the joint version (T-1-2) back into the original language (RT1 and RT2) to identify inconsistencies. Finally, a final version of the questionnaire was obtained. For content validation a committee of experts (seven women affected by breast cancer) assessed the degree of clarity, accuracy and understanding of each of the items in the questionnaire translated into Spanish, and calculated the content validity index (CVI) of the questionnaire according to Lawshe and Tristán. RESULTS: The LTQL questionnaire was translated into Spanish with a low discrepancy between translators. An adequate CVI higher than 0.58 was obtained in clarity (0.95), precision (0.93), comprehension (0.91) and relevance (0.72). CONCLUSIONS: The LTQL is a useful questionnaire in the health field for the assessment of quality of life of women survivors of long-term breast cancer.

OBJETIVO: La calidad de vida de mujeres afectadas de cáncer de mama diagnosticadas hace 5 o más años ha sido relativamente poco explorada en España, no existen instrumentos para su medida validados. El objetivo del estudio fue traducir al castellano, adaptar culturalmente y examinar la validez de contenido del cuestionario Long-Term Quality of Life Instrument (LTQL). METODOS: La traducción inicial fue realizada por dos traductores con castellano como lengua materna que tradujeron independientemente el cuestionario (versiones T1 y T2). Se realizó un análisis de los resultados y se elaboró una única versión preliminar en castellano (T-1-2). La retrotraducción se realizó por dos traductores con inglés como lengua materna que tradujeron independientemente la versión conjunta (T-1-2) al idioma original (RT1 y RT2) para identificar inconsistencias.

Cyclin D1 expression in Rosai-Dorfman disease: a near-constant finding that is not invariably associated with mitogen-activated protein kinase/extracellular signal-regulated kinase pathway activation.

Activating mutations in the mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) pathway have been shown in nearly half of the cases of Rosai-Dorfman disease (RDD). Cyclin D1, a key cell cycle regulator, constitutes a major downstream target of the MAPK/ERK pathway. In this study, we aim to further understand the pathogenesis of RDD by assessing the lesional histiocytes for cyclin D1, p-ERK, Ki-67, and BCL-2 by immunohistochemistry. We assessed 35 samples of RDD and a control group of histiocyte-rich reactive lesions. Cyclin D1 was expressed in about 90% of cases of RDD. Cyclin D1 was positive in 25-95% (median, 85%) of lesional histiocytes, was moderately/strongly expressed in 97% of cyclin D1-positive cases, and was significantly higher than in control specimens. p-ERK was positive in 16 of 30 (53%) cases of RDD and was negative in all controls. All p-ERK-positive RDD cases had concurrent cyclin D1 expression, whereas more than a third of cyclin D1-positive cases were negative for p-ERK. Ki-67 was low in RDD (median, 3%). BCL-2 was positive in lesional histiocytes in nine of 10 RDD cases assessed. Overall, these findings point to unexpected, potential roles of these molecules in the pathogenesis of RDD. Overexpression of cyclin D1 in the absence of ERK phosphorylation in a subset of RDD cases opens the possibility of oncogenic mechanisms bypassing ERK and supports the notion that cyclin D1 overexpression in RDD is multifactorial. Moreover, the observed lack of correlation between cyclin D1 with Ki-67 proliferative index suggests that prosurvival actions of cyclin D1 are, at least in part, cell cycle independent. Finally, expression of BCL-2 and the low Ki-67 index suggest that RDD might be driven by antiapoptotic rather than proproliferative oncogenic mechanisms.

Validación transcultural del HypoA-Q para medir conciencia de hipoglucemia en pacientes diabéticos / Cross-cultural validation of the HypoA-Q to measure hypoglycemic awareness in diabetic patients / Validação transcultural do HypoA-Q para mensurar consciência de hipoglicemia em pacientes diabéticos

Introducción: La hipoglucemia inadvertida incrementa el riesgo de la hipoglucemia severa en pacientes con diabetes. Una medición objetiva de la misma requiere instrumentos como el HypoA-Q, que, a diferencia de otros, mide conciencia de episodios nocturnos; sin embargo, no se dispone de una versión en español. Objetivo: Traducir y adaptar culturalmente la escala HypoA-Q para la medición de conciencia de la hipoglucemia en pacientes colombianos con Diabetes Mellitus. Metodología: Estudio de Adaptación transcultural del instrumento Hy-poA-Q. Se obtuvo la autorización de la autora para su traducción y adaptación a la población colombiana. Se siguió la metodología de la European Organisation for Research and Treat-ment for Cancer (EORTC). Al respecto, se realizaron dos traducciones directas por hablantes nativos del español, una versión reconciliada, dos traducciones inversas por dos hablantes nativos del inglés y una prueba piloto en 15 pacientes con diagnóstico de diabetes. Resulta-dos: Aunque las traducciones directas al español fueron similares, se hicieron ajustes para obtener una versión reconciliada con palabras más fáciles de comprender cambiando las uni-dades de mmol/L a mg/dl. Las traducciones inversas fueron similares al original en inglés. La prueba piloto, realizada en 15 pacientes, no requirió ajustar ningún ítem, pues la frecuencia de ítems con dificultades de comprensión, confusión o palabras ofensivas fue menor al 15%. Conclusiones: Se dispone de la versión en español para Colombia de la escala HypoA-Q. Se aconseja realizar un estudio de evaluación de sus propiedades psicométricas antes de ser usada en investigaciones o en la práctica clínica

Differences in Dietary Habits, Physical Exercise, and Quality of Life between Patients with Obesity and Overweight.

BACKGROUND: Overweight and obesity differ in their repercussions on the health and health-related quality of life (HRQoL) of patients. The objective of this study was to compare physical activity levels and dietary habits before admission and HRQoL at discharge between patients with obesity and overweight. METHODS: A cross-sectional study was undertaken among participants in a clinical trial on education for healthy eating and physical activity, enrolling non-diabetic patients admitted to Internal Medicine Departments. These were classified by body mass index (BMI) as having overweight (25-29.9 Kg/m2) or obesity (≥30 kg/m2). Data were gathered on sociodemographic characteristics, clinical variables (medication for anxiety/depression, Charlson Comorbidity Index, length of hospital stay), physical exercise and diet (International Physical Activity and Pardo Questionnaires), and HRQoL (EQ-5D-5L). The study included 98 patients with overweight (58.2% males) and 177 with obesity (52% males). RESULTS: In comparison to patients with obesity, those with overweight obtained better results for regular physical exercise (p = 0.007), healthy diet (p = 0.004), and "emotional eating" (p = 0.017). No between-group difference was found in HqoL scores. CONCLUSION: Patients with overweight and obesity differ in healthy dietary and physical exercise behaviors. Greater efforts are warranted to prevent an increase in the BMI of patients, paying special attention to their state of mind.

Tubular colonic duplication in an adult patient with long-standing history of constipation and tenesmus.

BACKGROUND: Intestinal duplications are rare congenital developmental anomalies with an incidence of 0.005-0.025% of births. They are usually identified before 2 years of age and commonly affect the foregut or mid-/hindgut. However, it is very uncommon for these anomalies, to arise in the colon or present during adulthood. CASE PRESENTATION: Herein, we present a case of a 28-year-old woman with a long-standing history of constipation, tenesmus, and rectal prolapse. Colonoscopy results were normal. An abdominal computed tomography (CT) revealed a diffusely mildly dilated redundant colon, which was prominently stool-filled. The gastrografin enema showed ahaustral mucosal appearance of the sigmoid and descending colon with findings suggestive of tricompartmental pelvic floor prolapse, moderate-size anterior rectocele, and grade 2 sigmoidocele. A laparoscopic exploration was performed, revealing a tubular duplicated colon at the sigmoid level. A sigmoid resection rectopexy was performed. Pathologic examination supported the diagnosis. At 1-month follow-up, the patient was doing well without constipation or rectal prolapse. CONCLUSIONS: Tubular colonic duplications are very rare in adults but should be considered in the differential diagnosis of chronic constipation refractory to medical therapy. Due to the non-specific manifestations of this entity, it is rather challenging to make an accurate diagnosis pre-operatively. Surgery remains the mainstay of treatment. Some reports suggest that carcinomas are more prone to develop in colonic/rectal duplications than in other GI tract duplications.

Rare thymopharyngeal duct cyst presentation in an adult patient.

Retained thymic tissue may occur anywhere along the path of descent of the thymus. Cervical thymic cysts are a rare cause of benign neck masses. Thymopharyngeal duct cysts are thymic cysts that span the length of the neck and extend towards the mediastinum. These lesions are rare and classically have been described in paediatric patients. Here, we present the case of a 23-year-old woman with a left-sided neck mass, which was found to be a thymopharyngeal duct cyst. Multiple analytic modalities including the clinical presentation, imaging, operative findings and histology were required to confirm the diagnosis and are discussed below.
