Impact of digital technologies upon teaching and learning in higher education in Latin America: an outlook on the reach, barriers, and bottlenecks.

Digital technology and literacy can heighten the transformation of teaching and learning in higher education institutions (HEIs). This study uncovers the extent to which digital technologies have been used to advance the teaching and learning process in HEIs, and the barriers and bottlenecks to why it may not have been effectively implemented across the HEIs. The study used nine selected countries in Latin America (LATAM) based on the main focus of the educators, commercial, and financial investors; to show the level of impact/implications of computer technologies on the teaching and learning processes. We applied a two-step (mixed) methodology (through a quantitative and qualitative lens) for the research investigation, using data collected from survey we administered to faculty members in HEIs across the different countries in LATAM. In turn, we implemented a Text Mining technique (sentiment and emotional valence analysis) to analyze opinions (textual data) given by the participants to help determine challenges and obstacles to using the digital technologies for teaching and learning in the region. Quantitatively, we applied a Kruskal-Wallis H-test to analyze the collected multiple choice and ranked items in the questionnaire in order to identify prominent factors that consummately influence the reach, barriers, and bottlenecks, and where the differences may lie across the different LATAM countries. The results show that the users upheld the emphasis on lack of training, infrastructures and resources, access to internet and digital platforms, as the main challenges to the teaching-learning process. The study also empirically discussed and shed light on critical factors the HEIs, particularly in LATAM, should resolve and adopt in support of the decision-making strategies, operational policies and governance, financial investments, and policymaking, at a time when "digital technologies" have become an inevitable and indispensable part of education and learning.

T-cell receptor signaling in Schimke immuno-osseous dysplasia is SMARCAL1-independent.

Schimke immuno-osseous dysplasia (SIOD) caused by mutations in SMARCAL1 is an ultra-rare disease characterized by specific facial features, skeletal dysplasia, and steroid-resistant nephrotic syndrome, which often leads to kidney failure and requires transplantation. Cellular (T-cell) deficiency, lymphopenia, and infections have been frequently reported, but whether they are due to T-cell-intrinsic defects in T-cell receptor (TCR) signaling associated with SMARCAL1 deficiency or to T-cell-extrinsic effects such as the impaired proliferation of hematopoietic precursors or T-cell-specific immunosuppression after renal transplantation remains unknown. We have explored the effects of SMARCAL1 deficiency on T-cell receptor signaling in primary and immortalized T cells from a 9-year-old SIOD patient under immunosuppression treatment when compared to healthy donors. Immortalized T cells recapitulated the SMARCAL1 deficiency of the patient, as judged by their impaired response to gamma irradiation. The results indicated that TCR-mediated signaling was normal in SIOD-derived immortalized T cells but strongly impaired in the primary T cells of the patient, although rescued with TCR-independent stimuli such as PMA + ionomycin, suggesting that SIOD-associated T-cell signaling is not intrinsically defective but rather the result of the impaired proliferation of hematopoietic precursors or of T-cell-specific immunosuppression. The lack of early thymic emigrants in our patients may support the former hypothesis.

Keeping it together: The role of social integration on health and psychological well-being among individuals with multiple sclerosis.

Research indicates that people with multiple sclerosis (MS) are more likely to report poorer health and well-being than their peers without MS. Fortunately, it is also known that an individual's social and lifestyle factors play a great role on maintaining and promoting one's health and overall well-being. The present study aimed to examine the role that social integration and social support, in particular have on health and psychological well-being (PWB) among individuals with MS. One hundred and eighty three individuals with MS completed measures of social and lifestyle factors, personality, physical and mental health, MS disease symptomatology and PWB. Cross sectional, regression analyses were conducted to determine the role of social and other lifestyle factors (e.g., diet/exercise) on health and PWB. A subset of this sample (108) completed a follow-up assessment. Longitudinal analyses of this sample were also conducted. Consistent with previous findings, the presence of social integration and social support were significant predictors of health and PWB even when taking into account other lifestyle factors (i.e., diet/exercise, substance use, smoking), cardiovascular risk, demographics (i.e., gender, age, education, relationship status) and personality. The role of social integration and support on health and PWB is well established. Present findings confirmed these associations among individuals with MS. These findings suggest that social integration and social support should be a crucial part of MS management and that further interventional studies aimed at improving social integration and reducing social isolation are warranted in an effort to promote and maintain overall health and well-being.

SARS-CoV-2 infection in early first-trimester miscarriages: a prospective observational study.

RESEARCH QUESTION: Is there an association between SARS-CoV-2 infection and first-trimester miscarriage? DESIGN: This multicentre prospective study included a cohort of women with first-trimester miscarriages registered consecutively by seven Spanish hospitals where universal PCR screening for SARS-CoV-2 infection was implemented with both miscarriages and deliveries. The incidence of SARS-CoV-2 infection among women with first-trimester miscarriages was compared with the rate registered in women on admission to the delivery ward within the same time frame using a mixed-effects Poisson regression analysis, considering 'hospital' as random effect. The characteristics of SARS-CoV-2 positive and negative patients who miscarried were compared through two-sided univariable analyses. RESULTS: A total of 301 miscarriages were registered, 11 (3.7%) to SARS-CoV-2 infected and 290 to non-infected women. In the same time frame as the miscarriages, 1936 deliveries were registered, 44 [2.3%] of them were SARS-CoV-2 infected. No differences in terms of SARS-CoV-2 infection incidence were observed between infected miscarriages and infected deliveries (P = 0.233). Regarding the differences observed between miscarriages in SARS-CoV-2 positive and negative women, more inevitable miscarriages occurred in the group of infected women (36.4% versus 16.5% in non-infected women; P = 0.004), and there was greater surgical management of miscarriages (27.3% versus 8.2% in non-infected women; P = 0.036), probably in line with the greater number of inevitable miscarriages observed in this group. CONCLUSIONS: No association between SARS-CoV-2 infection and risk of first-trimester miscarriage was observed; however, the type of miscarriage seems to differ between SARS-CoV-2 positive and negative women, with inevitable miscarriage being more frequent among infected women.

Piometra secundario a estenosis cervical en una adolescente / Pyometra secondary to cervical stenosis in an adolescent

INTRODUCCIÓN: El piometra es una afección infrecuente, pero grave, que en general se diagnostica en mujeres posmenopáusicas. En adolescentes es sumamente raro, y si se acompaña de amenorrea primaria hay que tener en mente las anomalías congénitas. CASO CLÍNICO: Adolescente de 13 años, sin antecedentes personales de interés salvo amenorrea primaria, que acude con abdomen agudo y es intervenida por una peritonitis difusa causada por un piometra secundario a disgenesia (estenosis) cervical congénita. Se realizó dilatación cervical y se dejó una sonda vesical intrauterina para prevenir la reestenosis. CONCLUSIONES: Un diagnóstico precoz y un tratamiento conservador con dilatación cervical y colocación temporal de un catéter urinario son esenciales para un manejo seguro y efectivo de la estenosis cervical en adolescentes.

INTRODUCTION: Pyometra is an uncommon but serious condition that is generally diagnosed in postmenopausal women. In adolescents it is extremely rare; if accompanied by primary amenorrhea, consider congenital abnormalities. CASE REPORT: A 13-year-old adolescent, with no relevant personal history except primary amenorrhea, who presented with an acute abdomen and was operated on for diffuse peritonitis caused by pyometra secondary to congenital cervical dysgenesis (stenosis). Cervical dilation was performed and a urinary catheter was temporarily placed inside the uterus to prevent restenosis. CONLUSIONS: An early diagnosis and conservative treatment with cervical dilation and temporary placement of a urinary catheter are essential for the safe and effective management of cervical stenosis in adolescents.

Functional Assessment of Fatigue and Other Patient-Reported Outcomes in Patients Enrolled in the Global aHUS Registry.

INTRODUCTION: Atypical hemolytic uremic syndrome (aHUS) is a progressive and potentially life-threatening disease characterized by complement-mediated thrombotic microangiopathy. Patients with aHUS may experience fatigue, which can negatively impact their lives, but there is a knowledge gap regarding disease burden in these patients. METHODS: In this longitudinal study, patients with aHUS from the Global aHUS Registry who completed patient-reported outcome assessments (Functional Assessment of Chronic Illness Therapy-Fatigue scale [FACIT-Fatigue], general health status, and work status) at ≥2 time points were assessed relative to treatment status: (i) never treated with eculizumab; (ii) on eculizumab at registry enrollment and continued therapy; and (iii) started eculizumab after registry enrollment. RESULTS: Patients who started eculizumab after the baseline visit (n = 23) exhibited improvements in fatigue (nearly 75% achieved clinically meaningful improvement), improved general health status (55%), and 25% to 30% rate reduction in symptoms of fatigue, weakness, irritability, nausea/vomiting, and swelling at last follow-up. Among patients already on eculizumab at registry enrollment (n = 295) and those never treated (n = 233), these parameters changed minimally relative to the baseline. Emergency room visits and hospital admissions were similar between groups. The number of health care provider visits and work days missed were higher in patients who started eculizumab after registry enrollment. CONCLUSION: These real-world findings confirm the detrimental effects of aHUS on patients' daily lives, including high levels of fatigue and impairments in general health status. The results suggest clinically meaningful improvement in fatigue, other patient-reported outcomes, and symptoms with eculizumab initiation after enrollment into the aHUS registry.

OBJECTIVE: Decision making in hospitals, and especially in their own healthcare services, is hardly referenced in the literature. During the pandemic period, healthcare services have put in place contingency plans to minimize the consequences of the coronavirus on professionals and patients. However, the deployment of contingency plans and results are hardly shared, depriving other services of references to refute, compare or emulate the aforementioned plans. The objective of this work was the description of the implementation and evaluation of Contingency Plans in the Covid-19 pandemic in a unit of inflammatory bowel disease of a Digestive Service in the Sanitary Area of Pontevedra and O Salnés. METHODS: A team of managers and professionals adapted the 10 measures recommended by Deloitte to face a pandemic to the healthcare environment. The measures were then formulated as a checklist. From the Plan-Do-Check-Act improvement cycle, they were grouped into categories: risk management, organizational management and decision-making. Finally, an external team carried out a qualitative evaluation of the implementation of the contingency plan carried out. RESULTS: The Intestinal Inflammatory Disease Unit of the Digestive Service has obtained an assessment of compliance with the 10 recommended measures to confidently face a pandemic. CONCLUSIONS: Sharing the deployment of the contingency plan and its results is useful to identify good practices. This article shows a method to evaluate decision-making in pandemic situations. The outcomes faces the The Intestinal Inflammatory Disease Unit in an excelent position.

Mastitis granulomatosa idiopática recurrente tratada con dapsona: reporte de un caso / Recurrent idiopathic granulomatous mastitis treated with dapsone: a case report

La mastitis granulomatosa idiopática (IGM, por sus siglas en inglés) es una afección inflamatoria crónica infrecuente y benigna de los senos. Puede simular tres trastornos mamarios muy frecuentes: carcinoma de mama, mastitis y absceso mamario. La IGM se presenta típicamente como una masa mamaria unilateral y dolorosa. La etiología de la IGM no está bien definida, pero se ha propuesto que podría ser una reacción inmune localizada del tejido mamario.El diagnostico de IGM recurrente es complejo porque los hallazgos clínicos y radiológicos no son específicos, por lo que el estudio histopatológico es crucial. El cáncer de mama, la inflamación gra-nulomatosa infecciosa y no infecciosa deben des-cartarse. El tratamiento de la IGM es controver-tido, e incluye vigilancia estrecha, medicamentos inmunosupresores, antibióticos si hay evidencia de infección y escisión quirúrgica. Presentamos un caso de IGM recurrente tratada con dapsona, con buena respuesta a tratamiento, demostrando que este fármaco podría ser una buena alternativa terapéutica debido a su efecto inmunomodulador, antiinflamatorio y ahorrador de esteroides.

Idiopathic granulomatous mastitis (IGM) is an uncommon, non-malignant, chronic inflamma-tory breast condition. It can mimic three very fre-quent breast disorders: breast carcinoma, mastitis and breast abscess. IGM typically presents as a unilateral and painful breast mass. The etiology of IGM is not well defined, but it has been pro-posed that it could be localized immune reaction to breast tissue. The diagnosis of recurrent IGM is complex be-cause clinical and radiological findings are nons-pecific, therefore histopathologic evaluation is crucial. Breast cancer and infectious and nonin-fectious granulomatous inflammation should be discarded. Treatment of IGM is controversial, including close monitoring, immunosuppressive drugs, antibiotics if there is infection evidence and surgical excision. This is a case report of recurrent IGM treated with Dapsone, with good response to treatment, showing that this drug could be a good therapeutic alternative due to its immunomodulatory and anti-inflammatory and steroid sparing.

Intrapartum and perinatal results associated with different degrees of staining of meconium stained amniotic fluid.

OBJECTIVE: To determine the intrapartum and perinatal results associated with different degrees of staining of meconium stained amniotic fluid (MSAF). STUDY DESIGN: In a retrospective cohort study of all singleton deliveries over a period of one year (2015) in a tertiary hospital, we compared different degrees of MSAF (yellow, green and thick) to clear amniotic fluids, and analysed in each group maternal, intrapartum and neonatal variables as well as umbilical cord blood gas analysis. RESULTS: Of the 3590 deliveries included, 503 (14%) had MSAF. The incidence of MSAF rises with gestational age at delivery, reaching 20.7% in gestations above 41 weeks compared to 4.3% below 37 weeks. As the amniotic fluid staining progresses we found a higher proportion of intrapartum fevers (p < 0.001), pathological fetal heart rate patterns (p < 0.05), operative vaginal deliveries and cesarean sections (p < 0.001), as well as the need for advanced neonatal resuscitation (p < 0.001). There was also a correlation between MSAF and low Apgar scores at five minutes (p < 0.001) and fetal-neonatal mortality (p < 0.001) but there was not a higher proportion of neonatal intensive care admissions (p > 0.05). We have observed a similar distribution of umbilical artery pH ranges in all groups (p > 0.05). CONCLUSIONS: MSAF was associated with an increase in the rate of pathological fetal heart rate patterns, intrapartum fevers, operative vaginal and cesarean section deliveries, need for neonatal resuscitation, low Apgar scores and higher fetal-neonatal mortality. Moreover, we found that the risks increase as the staining and consistency of the amniotic fluid evolves so it should alert the obstetrician and paediatrician to the potential adverse outcomes.

[Extranodal Natural Killer/T-Cell Lymphoma, nasal-type with primary cutaneous involvement. A case report]. / Linfoma NK/T extra nodal, tipo nasal, con compromiso cutáneo primario. Reporte de un caso.

INTRODUCTION: Extranodal natural killer/T-cell lymphoma (NK/T), nasal type, is an infrequent neoplasm with a high lethality, characterized by bone destruction around the sinus, nasal septum or obstruction of the airway. Also, may be primary skin involvement, airway and other organs. Objecti ve: Submit a rare condition in the pediatric population, in order to facilitate the diagnostic suspicion and quick recognition from specialists. CASE REPORT: a 14-year-old girl, who presented arm and leg lesions, painless, suggestive of subcutaneous panniculitis, which evolve to ulcerated purple maculae. Skin biopsy showed lesion compatible with NK/T lymphoma, nasal type. She was referred to pedia tric oncology, where she received chemotherapy treatment. Despite medical efforts, the patient died eight months after due to a serious pulmonary infection secondary to immunosuppression. Conclu sions: Extranodal NK/T-cell lymphoma, nasal type, is a rare neoplasm that behaves aggressively, with high mortality without treatment, therefore, its recognition has a high importance for early diagnosis and prompt referral to Hematology-Oncology.

Acrokeratoelastoidosis of the Foot with Clinical, Dermoscopic, Ultrasonographic, and Histopathologic Correlation.

Acrokeratoelastoidosis (AKE) is a rare form of focal acral keratoderma of unknown cause that typically begins during childhood and manifests with multiple, small, hyperkeratotic papules located over the lateral margins of the hands and feet. The purpose of this article is to report a pediatric case of AKE with dermoscopic, sonographic, and histopathologic descriptions, contributing to the awareness of this clinical diagnosis. We describe a 7-year-old girl with nonpainful yellowish papules on the lateral and medial aspects of both feet. Dermoscopy showed yellowish, structureless, linear areas. The sonographic appearance was suggestive of benignancy and ruled out the presence of piezogenic pedal papules and granulomas. Histopathology was consistent with AKE, showing acral skin with hyperorthokeratosis, hypergranulosis, and elastorrhexis in the reticular dermis. Acrokeratoelastoidosis may be difficult to recognize clinically because of its resemblance to other focal acral keratodermas. Color Doppler ultrasound can be a useful noninvasive tool for diagnosis and can confirm its benign appearance, although histopathology confirms the definitive diagnosis. To date, the dermoscopic description and ultrasound morphology of AKE have not been reported.

Linfoma NK/T extra nodal, tipo nasal, con compromiso cutáneo primario: reporte de un caso / Extranodal Natural Killer/T-Cell Lymphoma, nasal-type with primary cutaneous involvement: a case report

INTRODUCCIÓN: El linfoma extranodal natural killer/célula T (NK/T) de tipo nasal, es una neoplasia poco frecuente, con una alta letalidad, caracterizada por destrucción ósea alrededor de los senos paranasales, el septum nasal u obstrucción de la vía aérea. Puede presentar compromiso primario de la piel, vía aérea y otros órganos. OBJETIVO: Presentar un caso ilustrativo de una afección poco frecuente y de curso agresivo en población pediátrica, para facilitar la sospecha diagnóstica y el rápido reconocimiento por parte de los especialistas. CASO CLÍNICO: Adolescente de 14 años, que consultó por lesiones solevantadas en brazos y piernas, no dolorosas, sugerentes de paniculitis subcutánea, las cuales evolucionaron a máculas violáceas ulceradas. La biopsia de las lesiones fue compatible con linfoma NK/T de tipo nasal. Fue derivada a oncología pediátrica, donde recibió tratamiento quimioterápico. Pese a los esfuerzos médicos, la paciente falleció a los 8 meses producto de una infección pulmonar grave secundaria a inmunosupresión. CONCLUSIONES: El linfoma extranodal NK/T, tipo nasal es una neoplasia poco frecuente, que se comporta de forma agresiva, con una alta mortalidad sin tratamiento. Por lo que su reconocimiento es de gran relevancia para el diagnóstico precoz y rápida derivación a Hemato-Oncología.

[DRESS syndrome in paediatrics: Clinical case]. / Síndrome de sensibilidad a fármacos con eosinofilia y síntomas sistémicos en pediatría: Caso clínico.

Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare, potentially life-threatening, drug-induced hypersensitivity reaction that includes skin eruption, haematological abnormalities, lymphadenopathy, and internal organ involvement. OBJECTIVE: Presenting a rare condition in children, to facilitate a rapid diagnostic suspicion and recognition by doctors. CASE REPORT: An 9 months old infant admitted due to a severe viral pneumonia, managed with non-invasive ventilation and ceftriaxone. Five days after stopping antibiotics, a confluent maculopapular rash appeared, which was predominantly in the trunk, face and upper extremities, combined with a fever, eosinophilia, and elevated serum levels of transaminase. She received treatment with oral prednisone and topical corticosteroids for 6 weeks, with a good outcome after 3 months. CONCLUSIONS: The diagnosis of DRESS syndrome is made using clinical criteria, laboratory values, and histopathology, if there is any query. Although it is classically caused by anticonvulsants and sulphonamides, many other drugs have been implicated. The offending drug should be immediately discontinued and the patient given supportive treatment, and systemic corticosteroids for long periods of treatment.

Accurate Diagnosis of Severe Hypospadias Using 2D and 3D Ultrasounds.

The hypospadias is the most common urogenital anomaly of male neonates but the prenatal diagnosis of this is often missed before birth. We present the prenatal diagnosis of a severe penoscrotal hypospadias using 2D and 3D ultrasounds. 3D sonography allowed us the best evaluation of the genitals and their anatomical relations. This ample detailed study allowed us to show the findings to the parents and the pediatric surgeon and to configure the best information about the prognosis and surgical treatment.

Safety and risk factors for difficult endoscopist-directed ERCP sedation in daily practice: a hospital-based case-control study

Background: There are limited data concerning endoscopistdirected endoscopic retrograde cholangiopancreatography deep sedation. The aim of this study was to establish the safety and risk factors for difficult sedation in daily practice. Patients and methods: Hospital-based, frequency matched case-control study. All patients were identified from a database of 1,008 patients between 2014 and 2015. The cases were those with difficult sedations. This concept was defined based on the combination of the receipt of high-doses of midazolam or propofol, poor tolerance, use of reversal agents or sedation-related adverse events. The presence of different factors was evaluated to determine whether they predicted difficult sedation. Results: One-hundred and eighty-nine patients (63 cases, 126 controls) were included. Cases were classified in terms of high-dose requirements (n = 35, 55.56%), sedation-related adverse events (n = 14, 22.22%), the use of reversal agents (n = 13, 20.63%) and agitation/discomfort (n = 8, 12.7%). Concerning adverse events, the total rate was 1.39%, including clinically relevant hypoxemia (n = 11), severe hypotension (n = 2) and paradoxical reactions to midazolam (n = 1). The rate of hypoxemia was higher in patients under propofol combined with midazolam than in patients with propofol alone (2.56% vs. 0.8%, p < 0.001). Alcohol consumption (OR: 2.674 [CI 95%: 1.098-6.515], p = 0.030), opioid consumption (OR: 2.713 [CI 95%: 1.096-6.716], p = 0.031) and the consumption of other psychoactive drugs (OR: 2.015 [CI 95%: 1.017-3.991], p = 0.045) were confirmed to be independent risk factors for difficult sedation. Conclusions: Endoscopist-directed deep sedation during endoscopic retrograde cholangiopancreatography is safe. The presence of certain factors should be assessed before the procedure to identify patients who are high-risk for difficult sedation (AU)

The aim of this study was to establish the safety and risk factors for difficult sedation in daily practice. PATIENTS AND METHODS: Hospital-based, frequency matched case-control study. All patients were identified from a database of 1,008 patients between 2014 and 2015. The cases were those with difficult sedations. This concept was defined based on the combination of the receipt of high-doses of midazolam or propofol, poor tolerance, use of reversal agents or sedation-related adverse events. The presence of different factors was evaluated to determine whether they predicted difficult sedation. RESULTS: One-hundred and eighty-nine patients (63 cases, 126 controls) were included. Cases were classified in terms of high-dose requirements (n = 35, 55.56%), sedation-related adverse events (n = 14, 22.22%), the use of reversal agents (n = 13, 20.63%) and agitation/discomfort (n = 8, 12.7%). Concerning adverse events, the total rate was 1.39%, including clinically relevant hypoxemia (n = 11), severe hypotension (n = 2) and paradoxical reactions to midazolam (n = 1). The rate of hypoxemia was higher in patients under propofol combined with midazolam than in patients with propofol alone (2.56% vs. 0.8%, p < 0.001). Alcohol consumption (OR: 2.674 [CI 95%: 1.098-6.515], p = 0.030), opioid consumption (OR: 2.713 [CI 95%: 1.096-6.716], p = 0.031) and the consumption of other psychoactive drugs (OR: 2.015 [CI 95%: 1.017-3.991], p = 0.045) were confirmed to be independent risk factors for difficult sedation. CONCLUSIONS: Endoscopist-directed deep sedation during endoscopic retrograde cholangiopancreatography is safe. The presence of certain factors should be assessed before the procedure to identify patients who are high-risk for difficult sedation.
