Effects of Transition from Remote to In-Person Learning in University Students: A Longitudinal Study.

Previous studies have shown that the transition from the University environment to remote learning impacted student mental health. Our study aimed to investigate the effects of university environment on anxiety and depressive symptoms in health sciences students. Students at the Technical University of Manabí, Ecuador, with 6-10 in-person semesters, who shifted to remote learning and then returned to face-to-face learning were selected. Students responded to the General Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9). In addition, questions regarding social interaction, physical exercise, mood and sleep habits were also asked. This longitudinal study tracked 323 students during the return to in-person classes and term end. The results showed similar rates of anxiety (GAD-7, p = 0.011-p = 0.002) and depression (PHQ-9 p = 0.001-p = 0.032) among students at week 1 and week 15. Previous diagnosis of depression (OR, 0.171; CI 0.050-0.579, p < 0.005) was shown to correlate with depression levels in week 1, with no changes seen at follow-up. Anxiety levels were shown to be associated with a previous diagnosis of the disorder at week 1, but not at follow-up (OR 0.233; CI 0.085-0.643, p < 0.005). The return to in-person learning among university students maintained levels of anxiety and depressive symptoms, underscoring ongoing vulnerabilities to mental health disorders in this group.

Insulin and the kidneys: a contemporary view on the molecular basis.

Insulin is a hormone that is composed of 51 amino acids and structurally organized as a hexamer comprising three heterodimers. Insulin is the central hormone involved in the control of glucose and lipid metabolism, aiding in processes such as body homeostasis and cell growth. Insulin is synthesized as a large preprohormone and has a leader sequence or signal peptide that appears to be responsible for transport to the endoplasmic reticulum membranes. The interaction of insulin with the kidneys is a dynamic and multicenter process, as it acts in multiple sites throughout the nephron. Insulin acts on a range of tissues, from the glomerulus to the renal tubule, by modulating different functions such as glomerular filtration, gluconeogenesis, natriuresis, glucose uptake, regulation of ion transport, and the prevention of apoptosis. On the other hand, there is sufficient evidence showing the insulin receptor's involvement in renal functions and its responsibility for the regulation of glucose homeostasis, which enables us to understand its contribution to the insulin resistance phenomenon and its association with the progression of diabetic kidney disease.

Hippocampal subfield volumes are associated with verbal memory after first-ever ischemic stroke.

INTRODUCTION: Hippocampal subfield volumes are more closely associated with cognitive impairment than whole hippocampal volume in many diseases. Both memory and whole hippocampal volume decline after stroke. Understanding the subfields' temporal evolution could reveal valuable information about post-stroke memory. METHODS: We sampled 120 participants (38 control, 82 stroke), with cognitive testing and 3T-MRI available at 3 months and 3 years, from the Cognition and Neocortical Volume after Stroke (CANVAS) study. Verbal memory was assessed using the Hopkins Verbal Learning Test-Revised. Subfields were delineated using FreeSurfer. We used partial Pearson's correlation to assess the associations between subfield volumes and verbal memory scores, adjusting for years of education, sex, and stroke side. RESULTS: The left cornu ammonis areas 2/3 and hippocampal tail volumes were significantly associated with verbal memory 3-month post-stroke. At 3 years, the associations became stronger and involved more subfields. DISCUSSION: Hippocampal subfield volumes may be a useful biomarker for post-stroke cognitive impairment.

Evaluation of CYP2C19 Gene Polymorphisms in Patients with Acid Peptic Disorders Treated with Esomeprazole.

BACKGROUND: CYP2C19 is a highly polymorphic gene that encodes an enzyme with the same name and whose function is associated with the metabolism of many important drugs, such as proton pump inhibitors (such as esomeprazole, which is used for the treatment of acid peptic disease). Genetic variants in CYP2C19 alter protein function and affect drug metabolism. This study aims to genotypically and phenotypically characterize the genetic variants in the CYP2C19 gene in 12 patients with acid peptic disorders and different therapeutic profiles to proton pump inhibitor (PPI) drugs. The patients were randomly selected from a controlled, randomized and blinded clinical pilot trial of 33 patients. We determined the presence and frequency of single nucleotide polymorphisms (SNPs) within exons 1-5 and 9, the intron-exon junctions, and a fragment in the 3' UTR region of the CYP2C19 gene using Sanger sequencing. Undescribed polymorphisms were analyzed by free online bioinformatics tools to evaluate the potential molecular effects of these genetic variants. RESULTS: We identified nine polymorphisms, six of which had no reported functions. One of these genetic variants, with a functional impact, not yet reported (p.Arg132Trp) was predicted by bioinformatic tools as potentially pathogenic. This finding suggests that p.Arg132Trp could be related to poor metabolizers of drugs metabolized by CYP2C19. CONCLUSION: We identified the genotype spectrum of variants in CYP2C19. The genotype spectrum of variants in CYP2C19 could predict the treatment response and could support to evaluate clinical efficacy in patients treated with esomeprazole.

[Anesthetic management of neonates undergoing diagnostic and therapeutic cardiac catheterization: a systematic literature review]. / Manejo anestésico de neonatos submetidos a cateterismo cardíaco diagnóstico e terapêutico: uma revisão sistemática da literatura.

BACKGROUND: Several interventional cardiology procedures are required in neonates with congenital heart disease. Interventional cardiology procedures have a higher risk of cardiac arrest compared to other interventions. At present, there is great heterogeneity in the perioperative management of congenital heart disease neonates undergoing diagnostic cardiac catheterization or therapeutic cardiac catheterization. STUDY OBJECTIVES: Primary aim: Provide a systematic review of the most effective and/or safe anesthetic and perioperative management in neonates with congenital heart disease who undergo diagnostic cardiac catheterization or therapeutic cardiac catheterization. Secondary aim: Identify the medications, monitoring parameters and airway management used in the same population. DESIGN: Systematic literature review. SETTING: Catheterization laboratory. METHODS: Literature was searched (December 2017) in electronic databases Medline, EMBASE, ScienceDirect, BIREME-Lilacs-Biblioteca Virtual de la Salud, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and Health Technology Assessment Database. MAIN RESULTS: From 130 records identified, four studies met inclusion criteria and quality assessment. None of the studies were relevant to the primary objective. Regarding the secondary objectives, one study compared the efficacy and adverse effects of racemic ketamine and its S(+) ketamine enantiomer, one study reported the efficacy of subarachnoid anesthesia for high-risk children undergoing diagnostic cardiac catheterization, one study identified the factors associated to high severity adverse events related to sedation, anesthesia and airway, and one study retrospectively analyzed cardiac catheterization procedures in neonates weighing less than 2.5 kg. CONCLUSION: There are no evidence-based recommendations available for congenital heart disease neonates undergoing cardiac catheterization. More studies are required to evaluate the ideal anesthetic and perioperative management in this population.

Patient Satisfaction with Medical Tourism: A Review of 460 International Plastic Surgery Patients in Colombia.

Cosmetic surgery is at the forefront of an exploding medical tourism industry. Patients are able to research options globally through the internet, and increasing numbers are seeking improved service, quality, and value through surgery overseas. Little work has been done to measure the patient experience when traveling for surgery and, to our knowledge, this is the largest study of its kind to examine patient satisfaction with medical tourism. METHODS: We retrospectively reviewed patient satisfaction surveys completed by 460 consecutive international patients receiving cosmetic surgery at a private plastic surgery practice in Cartagena, Colombia, between February 2016 and April 2018. RESULTS: Overall patient satisfaction was excellent, with 98.2% responding that they would refer us to friends and family. Patient satisfaction ratings across all other items was also very high (range: 97.1%-100%) for information provided, the surgeon, the staff, facilities, and payment. CONCLUSIONS: Excellent patient satisfaction is possible with medical tourism if the patient perceives and receives value through effective results, a pleasant experience, and favorable costs. These successes in plastic surgery medical tourism highlight the potential for significant continued growth in this sector as a whole.

APOE ɛ4 Carriers Show Delayed Recovery of Verbal Memory and Smaller Entorhinal Volume in the First Year After Ischemic Stroke.

BACKGROUND: The apolipoprotein E (APOE) gene ɛ4 allele is a risk factor for Alzheimer's disease and cardiovascular disease. However, its relationship with cognition and brain volume after stroke is not clear. OBJECTIVE: We compared cognition and medial temporal lobe volumes in APOEɛ4 carriers and non-carriers in the first year after ischemic stroke. METHODS: We sampled 20 APOEɛ4 carriers and 20 non-carriers from a larger cohort of 135 ischemic stroke participants in the longitudinal CANVAS study. Participants were matched on a range of demographic and stroke characteristics. We used linear mixed-effect models to compare cognitive domain z-scores (attention, processing speed, executive function, verbal and visual memory, language, visuospatial function) and regional medial temporal lobe volumes (hippocampal, entorhinal cortex) between groups at each time-point (3, 12-months post-stroke), and within groups across time-points. APOE gene single nucleotide polymorphisms (SNPs; rs7412, rs429358) were genotyped on venous blood. RESULTS: APOEɛ4 carriers and non-carriers did not differ on any demographic, clinical, or stroke variable. Carriers performed worse than non-carriers in verbal memory at 3 months post-stroke (p = 0.046), but were better in executive function at 12 months (p = 0.035). Carriers demonstrated a significant improvement in verbal memory (p = 0.012) and executive function (p = 0.015) between time-points. Non-carriers demonstrated a significant improvement in visual memory (p = 0.0005). Carriers had smaller bilateral entorhinal cortex volumes (p < 0.05), and larger right sided and contralesional hippocampal volumes, at both time-points (p < 0.05). CONCLUSION: APOE ɛ4 is associated with delayed recovery of verbal memory function and reduced entorhinal cortex volumes in the first year after ischemic stroke.

Plastic Surgery Medical Tourism in Colombia: A Review of 658 International Patients and 1,796 Cosmetic Surgery Procedures.

BACKGROUND: Cosmetic surgery is at the forefront of a $60 billion medical tourism industry. Patients are now able to research options globally through the internet, and increasing numbers are seeking improved service, quality, and value through surgery overseas. This study examines 658 consecutive patients receiving 1,796 cosmetic surgery procedures at a private plastic surgery practice in Cartagena, Colombia. METHODS: We retrospectively reviewed the medical records of 658 consecutive international patients receiving cosmetic surgery at a private plastic surgery practice in Cartagena, Colombia. RESULTS: Patients traveled to Colombia from 34 different countries spread across 6 continents. Ninety percent of patients came from North America. Patients from the United States represented 38 states and the District of Columbia, and Canadian patients represented 7 provinces. Eighty-three percent of patients were women and 90% were between the age of 20 and 54. The 658 patients in this study had a total of 1,796 cosmetic surgery procedures, involving 5,456 surgical sites. Seventy-two percent of patients received combination procedures with an average of 2.7 procedures per patient. Ninety-nine percent of cases were performed under general anesthesia and 100% were performed in an accredited hospital. CONCLUSIONS: Our data highlight trends defining plastic surgery medical tourism. Our data indicate that traveling for surgery is widely appealing, with women and men from diverse backgrounds traveling to Colombia from all over the world for a variety of procedures.

Influence of Severity on Aesthetic Outcomes of Unilateral Cleft Lip Repair in 1,823 Patients.

BACKGROUND: Although efforts to improve access to care for patients with cleft lip in the developing world have grown tremendously, there is a dearth of data regarding aesthetic outcomes after cleft lip repairs in this setting. Defining severity-outcome relationships has the potential to improve efficiency of care delivery in resource-limited settings, and to improve overall results. In this study, we investigate the relationship between initial cleft lip severity and early aesthetic outcomes following surgical repair of primary unilateral cleft lip. METHODS: Using previously validated tools to assess unilateral cleft lip severity and aesthetic outcome after repair, we evaluated 1,823 consecutive patients who underwent primary unilateral cleft lip/nose (UCL/N) repair. Three separate evaluators scored each case for a total of 5,469 total independent evaluations. RESULTS: Our results show that with increasing severity of UCL/N deformity, there is a corresponding decrease in early aesthetic outcome scores. Using our results, we established normative early aesthetic outcomes following repair for each severity grade of UCL/N deformity. CONCLUSIONS: In conclusion, this study has achieved a standardized, timely, and cost-effective evaluation of 1,823 surgical cases of primary UCL/N repair. This data set provides a normal distribution of aesthetic results according to initial cleft severity and defines a standard of "expected" aesthetic results after primary UCL/N repair. Our results also show a clear correlation between initial severity and immediate aesthetic result after surgery, though we also show that excellent results are possible regardless of initial cleft severity.

Improved Early Cleft Lip and Palate Complications at a Surgery Specialty Center in the Developing World.

OBJECTIVE: To evaluate complication rates following cleft lip and cleft palate repairs during the transition from mission-based care to center-based care in a developing region. PATIENTS AND DESIGN: We performed a retrospective review of 3419 patients who underwent cleft lip repair and 1728 patients who underwent cleft palate repair in Guwahati, India between December 2010 and February 2014. Of those who underwent cleft lip repair, 654 were treated during a surgical mission and 2765 were treated at a permanent center. Of those who underwent cleft palate repair, 236 were treated during a surgical mission and 1491 were treated at a permanent center. SETTING: Two large surgical missions to Guwahati, India, and the Guwahati Comprehensive Cleft Care Center (GCCCC) in Assam, India. MAIN OUTCOME MEASURE: Overall complication rates following cleft lip and cleft palate repair. RESULTS: Overall complication rates following cleft lip repair were 13.2% for the first mission, 6.7% for the second mission, and 4.0% at GCCCC. Overall complication rates following cleft palate repair were 28.0% for the first mission, 30.0% for the second mission, and 15.8% at GCCCC. Complication rates following cleft palate repair by the subset of surgeons permanently based at GCCCC (7.2%) were lower than visiting surgeons ( P < .05). CONCLUSIONS: Our findings support the notion that transitioning from a mission-based model to a permanent facility-based model of cleft care delivery in the developing world can lead to decreased complication rates.

Virological surveillance of Aedes (Stegomyia) aegypti and Aedes (Stegomyia) albopictus as support for decision making for dengue control in Medellín.

INTRODUCTION: Dengue represents an important public health problem in Colombia. No treatment is available and the vaccine has not been approved in all countries, hence, actions should be strengthened to mitigate its impact through the control of Aedes aegypti, the vector mosquito. In Colombia, surveillance is done using entomological indexes and case notification, which is usually informed late, leading to untimely interventions. Viral detection in urban mosquitoes using molecular techniques provides more accurate entomological information for decision-making. OBJECTIVE: To report results of virological surveillance in Aedes specimens collected during routine entomological activities of the Secretaría de Salud de Medellín. MATERIALS AND METHODS: Specimens were collected during two periods in each of which we selected 18 dwellings around each one of the 250 larva traps arranged for mosquitoe surveillance, as well as 70 educational institutions and 30 health centers. Specimens were identified morphologically, and divided in pools for viral detection using reverse transcription polymerase chain reaction (RT-PCR). We calculated the minimum infection rate and the adult infestation index for each group. RESULTS: We collected 1,507 adult mosquitoes, 10 of which were identified as A. albopictus. Out of the 407 pools, 132 (one of them Ae. albopictus) were positive, and 14.39% were A. aegypti males. The minimum infection rates for Ae. aegypti were 120.07 and 69,50 for the first and second periods, respectively, and the adult infestation index was higher in educational institutions (23.57%). CONCLUSIONS: Using RT-PCR we identified natural infectivity and vertical transmission of dengue virus in A. aegypti and A. albopictus. We suggest the use of molecular techniques in arbovirosis surveillance and control programs in Colombia.

Validation of a Unilateral Cleft Lip Surgical Outcomes Evaluation Scale for Surgeons and Laypersons.

BACKGROUND: A standardized evaluation tool is needed for the assessment of surgical outcomes in cleft lip surgery. Current scales for evaluating unilateral cleft lip/nose (UCL/N) aesthetic outcomes are limited in their reliability, ease of use, and application. The Unilateral Cleft Lip Surgical Outcomes Evaluation (UCL SOE) scale measures symmetry of 4 components and sums these for a total score. The purpose of this study was to validate the SOE as a reliable tool for use by both surgeons and laypersons. METHODS: Twenty participants (9 surgeons and 12 laypeople) used the SOE to evaluate 25 sets of randomly selected presurgical and postsurgical standardized photographs of UCL/N patients. Interrater reliability for surgeon and laypeople was determined using an intraclass correlation coefficient (ICC). RESULTS: Individual surgeons and laypeople both reached an ICC in the "fair to good" range (ICC = 0.42 and 0.59, respectively). Averaging 2 evaluators in the surgeon group improved the ICC to 0.58 and in the laypeople group to 0.74, respectively. Averaging 3 evaluators increased the ICC for surgeons to the "good" range (ICC = 0.71) and the ICC for laypeople to the "very good" range (ICC = 0.82). CONCLUSIONS: Surgeon and layperson raters can reliably use the SOE to assess the aesthetics results after surgical repair of UCL/N, and improved reliability and reproducibility is achieved by averaging the scores of multiple reviewers.

Validation of the Unilateral Cleft Lip Severity Index for Surgeons and Laypersons.

BACKGROUND: Severity of the primary unilateral cleft lip/nose deformity (UCL/N) is postulated to play a key role in postoperative complications, aesthetic result, and need for secondary surgery. There is no validated and widely accepted classification scheme of initial cleft severity. The purpose of this study was to validate the Unilateral Cleft Lip Cleft Severity Index as a reliable tool for evaluating presurgical UCL/N deformity by both surgeons and laypersons. METHODS: Twenty-five participants (10 surgeons and 15 laypeople) evaluated 25 sets of randomly selected presurgical standardized photographs of UCL/N patients. Each participant rated patients on a scale of 1-4 using the Cleft Severity Index. Interrater reliability for surgeons, laypersons, and all participants was determined using an intraclass correlation coefficient. Histograms and regression analysis were performed to compare average ratings between groups. RESULTS: Interrater reliability for all groups was classified as "very good" determined by intraclass correlation coefficients of 0.837 (laymen), 0.885 (surgeons), and 0.848 (all participants). These results indicate that there was a high degree of interrater across all 3 groups and that both surgeons and laypersons can reliability rate cleft severity using the Cleft Severity Index. CONCLUSIONS: This study validates the use of the Cleft Severity Index by both surgeons and laypersons as a reliable tool for evaluating the degree of presurgical severity of patients with UCL/N. The Unilateral Cleft Lip Cleft Severity Index can thus serve as a reproducible and reliable grading system for primary UCL/N deformity and to categorize patients for future outcomes studies.

Vigilancia virológica de Aedes (Stegomyia) aegypti y Aedes (Stegomyia) albopictus como apoyo para la adopción de decisiones en el control del dengue en Medellín / Virological surveillance of Aedes (Stegomyia) aegypti and Aedes (Stegomyia) albopictus as support for decision making for dengue control in Medellín

Resumen Introducción. El dengue en Colombia representa un grave problema de salud y, dado que no existe un tratamiento efectivo para la enfermedad y la vacuna no se ha aprobado en todos los países, se deben fortalecer acciones para mitigar su impacto mediante el control de Aedes aegypti, el mosquito vector. La vigilancia en el país se hace con base en los índices entomológicos y en la notificación de casos, la cual es frecuentemente tardía y por ello conduce a falta de oportunidad en las intervenciones. La detección viral en mosquitos urbanos mediante técnicas moleculares proporciona información entomológica más precisa para la adopción de decisiones. Objetivo. Reportar los resultados de la vigilancia virológica de especímenes de Aedes spp. recolectados durante actividades entomológicas rutinarias de la Secretaría de Salud de Medellín. Materiales y métodos. Los ejemplares se recolectaron durante dos periodos, en cada uno de los cuales se seleccionaron 18 viviendas alrededor de cada una de las 250 trampas para larvas dispuestas para la vigilancia entomológica, así como 70 instituciones educativas y 30 centros de salud. Los ejemplares se identificaron y se conformaron grupos para la detección viral mediante reacción en cadena de la polimerasa con transcripción inversa (Reverse Transcription Polymerase Chain Reaction, RT-PCR). Se calculó la tasa mínima de infección y el índice de infestación en adultos. Resultados. Se recolectaron 1.507 mosquitos, 10 de los cuales eran Ae. albopictus. De los 407 grupos conformados, 132 (uno de ellos de Ae. albopictus) fueron positivos, y 14,39 % correspondió a machos de Ae. aegypti. La tasa mínima de infección para Ae. aegypti fue de 120,07 y 69,50 en el primer y segundo períodos, respectivamente, y el índice de infestación en adultos fue mayor en las instituciones educativas (23,57 %). Conclusión. Mediante la RT-PCR se detectaron la infección natural y la transmisión vertical del virus del dengue en Ae. aegypti y en Ae. albopictus. Se propone considerar la incorporación de estas técnicas moleculares en los programas de vigilancia y control de las arbovirosis en el país.

Does left ventricular hypertrophy affect cognition and brain structural integrity in type 2 diabetes? Study design and rationale of the Diabetes and Dementia (D2) study.

BACKGROUND: Cognitive impairment is common in type 2 diabetes mellitus, and there is a strong association between type 2 diabetes and Alzheimer's disease. However, we do not know which type 2 diabetes patients will dement or which biomarkers predict cognitive decline. Left ventricular hypertrophy (LVH) is potentially such a marker. LVH is highly prevalent in type 2 diabetes and is a strong, independent predictor of cardiovascular events. To date, no studies have investigated the association between LVH and cognitive decline in type 2 diabetes. The Diabetes and Dementia (D2) study is designed to establish whether patients with type 2 diabetes and LVH have increased rates of brain atrophy and cognitive decline. METHODS: The D2 study is a single centre, observational, longitudinal case control study that will follow 168 adult patients aged >50 years with type 2 diabetes: 50% with LVH (case) and 50% without LVH (control). It will assess change in cardiovascular risk, brain imaging and neuropsychological testing between two time-points, baseline (0 months) and 24 months. The primary outcome is brain volume change at 24 months. The co-primary outcome is the presence of cognitive decline at 24 months. The secondary outcome is change in left ventricular mass associated with brain atrophy and cognitive decline at 24 months. DISCUSSION: The D2 study will test the hypothesis that patients with type 2 diabetes and LVH will exhibit greater brain atrophy than those without LVH. An understanding of whether LVH contributes to cognitive decline, and in which patients, will allow us to identify patients at particular risk.

Corticoterapia profiláctica transquirúrgica de la hiperplasia cicatricial. Estudio clínico-estadístico prospectivo / Trans-surgery prophylactic corticotherapy of cicatricial hyperplasia. Clinic-stadistic prospective study

Antecedentes y Objetivo. La hiperplasia cicatricial, denominación que reúne la cicatriz hipertrófica y el queloide, representa un gran desafío en la práctica quirúrgica. Estas patologías que solo acometen a los seres humanos, y en especial el queloide, se han asociado a las razas negra y amarilla, hecho corroborado en el estado de Bahía - Brasil, donde la afro-descendencia es muy significativa y donde gran número de mamoplastias de reducción se acompañan de hiperplasia cicatricial. Son anomalías que generan mucha insatisfacción en los pacientes y en los cirujanos. El objetivo del presente estudio es demostrar que se pueden prevenir este tipo de cicatrices antes de la incisión cutánea y antes del disparo de la cascada de reparación, moldeando las fases iniciales de la cicatrización con el uso de un corticoide especifico. Material y método. Planteamos un estudio prospectivo de prevalencia longitudinal y autocontrolado, en 60 mamas de 30 mujeres con diagnóstico de gigantomastia, a las que se les practico mamoplastia de reducción en T invertida e injerto de placa areola-papilar (Thorek-Pitanguy), comparando 2 grupos: el primero con 30 mamas derechas infiltradas con solución de corticoide antiquimiotaxico en dermis y subcutáneo, por debajo de la tinta del diseño de la marcación prequirúrgica y antes de las incisiones; y el segundo con 30 mamas izquierdas sin infiltración (grupo control), para determinar estadísticamente, después de un periodo de seguimiento, la eficacia profiláctica del acetato de dexametasona en la prevención de la hiperplasia cicatricial. Tras un seguimiento postoperatorio de 6 a 15 meses, clasificamos el tipo de cicatrización obtenido según la escala de Vancouver, con documentación fotográfica. Realizamos los estudios estadísticos con test de Chi-cuadrado y prueba de Kruskal-Wallis para análisis experimental. Resultados. Comprobamos una disminución estadísticamente significativa al comparar la presencia de hiperplasia cicatricial entre ambas mamas (p=0.02). La mama derecha, infiltrada con el corticoide, tuvo menos incidencia (p=0.06). Datos confirmados con la prueba estadística experimental. Conclusiones. La intervención terapéutica profiláctica del corticoide de depósito acetato de dexametasona, local, en el transoperatorio, es altamente eficaz disminuyendo significativamente la presencia de hiperplasia cicatricial (AU)

Background and Objective. Cicatricial hyperplasia, denomination which gathers the hypertrophic scar and keloid, represents a big challenge in surgical practice. These pathologies rushing only on human beings have been associated by different works, in particular the keloid, with black and yellow races, confirmed fact in the state of Bahia - Brazil, where large number of reduction mammoplasty, they are accompanied by hyperplasic scars and where the afro-descendant genetic is very significant. These anomalies generate great insatisfaction in patients and surgeons, Our objective is to demonstrate than we can prevent this type of scars before the skin incision, and before the firing of the cascade of repair, molding the early stages of healing using an specific corticoid. Methods. We conduct a prospective study of longitudinal prevalence and self-controlled, on 60 breast from 30 women with diagnostic of gigantomasty, all subject to reduction mammoplasty with T inverted and graft-mammillary areola plate (Thorek-Pitanguy), and comparing between 2 groups: the first one with 30 right breast infiltrated with a solution of corticoid anti-chemo attractant in the dermis and subcutaneous, under the surgical predial design ink and before incisions (intervention group); and the second one with 30 left breast without infiltration (control group), to statistically determine, after a period of monitoring, the prophylactic efficacy of dexamethasone acetate in preventing the hyperplasic scar. Patients were accompanied between 6-15 months, and their kind of healing was classified by the scale of Vancouver with photographic documentation. Statistical studies were made by the Chi-square test and the Kruskal-Wallis test for experimental analysis. Results. It is shown a significant reduction, statistically, in hyperplasic scar when compared the 2 breasts (p=0.02): the right breast infiltrated with corticoid had minor incidence (p=0.06). Data confirmed by the statistical experimental test. Conclusions. Prophylactic therapeutic intervention, intra-local, with dexamethasone acetate in the transoperative is highly effective, reducing significantly the presence of the hyperplasic scar (AU)

Primary Cleft Lip and Palate Repair in Assam, India: Does Preoperative Anthropometric Analysis Help Identify Patients With Increased Surgical Risk in a Clinically Prescreened Population?

OBJECTIVE: To compare anthropometric z-scores with incidence of post-operative complications for patients undergoing primary cleft lip or palate repair. DESIGN: This was a retrospective observational analysis of patients from a surgical center in Assam, India, and includes a cohort from a single surgical mission completed before the opening of the center. SETTING: Patients included in the study underwent surgery during an Operation Smile mission before the opening of Operation Smile's Guwahati Comprehensive Cleft Care Center in Guwahati, India. The remaining cohort received treatment at the center. All patients received preoperative assessment and screening; surgery; and postoperative care, education, and follow-up. PATIENTS, PARTICIPANTS: Our sample size included 1941 patients and consisted of all patients with complete information in the database who returned for follow-up after receiving primary cleft lip repair or primary cleft palate repair between January 2011 and April 2013. INTERVENTIONS: Preoperative anthropometric measurements. MAIN OUTCOME MEASURE(S): Postoperative complications. RESULTS: Anthropometric z-scores were not a significant predictor of adverse surgical outcomes in the group analyzed. Palate surgery had increased risk of complication versus lip repair, with an overall odds ratio of 5.66 (P < .001) for all patients aged 3 to 228 months. CONCLUSIONS: Anthropometric z-scores were not correlated with increased risk of surgical complications, possibly because patients were well screened for malnutrition before surgery at this center. Primary palate repair is associated with an approximate fivefold increased risk of developing postoperative complication(s) compared with primary lip repair.

Sun protection for preventing basal cell and squamous cell skin cancers.

BACKGROUND: 'Keratinocyte cancer' is now the preferred term for the most commonly identified skin cancers basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), which were previously commonly categorised as non-melanoma skin cancers (NMSC). Keratinocyte cancer (KC) represents about 95% of malignant skin tumours. Lifestyle changes have led to increased exposure to the sun, which has, in turn, led to a significant increase of new cases of KC, with a worldwide annual incidence of between 3% and 8%. The successful use of preventive measures could mean a significant reduction in the resources used by health systems, compared with the high cost of the treatment of these conditions. At present, there is no information about the quality of the evidence for the use of these sun protection strategies with an assessment of their benefits and risks. OBJECTIVES: To assess the effects of sun protection strategies (i.e. sunscreen and barrier methods) for preventing keratinocyte cancer (that is, basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) of the skin) in the general population. SEARCH METHODS: We searched the following databases up to May 2016: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trial registries and the bibliographies of included studies for further references to relevant trials. SELECTION CRITERIA: We included randomised controlled clinical trials (RCTs) of preventive strategies for keratinocyte cancer, such as physical barriers and sunscreens, in the general population (children and adults), which may provide information about benefits and adverse events related to the use of solar protection measures. We did not include trials focused on educational strategies to prevent KC or preventive strategies in high-risk groups. Our prespecified primary outcomes were BCC or cSCC confirmed clinically or by histopathology at any follow-up and adverse events. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies for eligibility using Early Review Organizing Software (EROS). Similarly, two review authors independently used predesigned data collection forms to extract information from the original study reports about the participants, methods of randomisation, blinding, comparisons of interest, number of participants originally randomised by arm, follow-up losses, and outcomes, and they assessed the risk of bias. We resolved any disagreement by consulting a third author and contacted trial investigators of identified trials to obtain additional information. We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included one RCT (factorial design) that randomised 1621 participants.This study compared the daily application of sunscreen compared with discretionary use of sunscreen, with or without beta-carotene administration, in the general population. The study was undertaken in Australia; 55.2% of participants had fair skin, and they were monitored for 4.5 years for new cases of BCC or cSCC assessed by histopathology. We found this study to be at low risk of bias for domains such as allocation, blinding, and incomplete outcome data. However, we found multiple unclear risks related to other biases, including an unclear assessment of possible interactions between the effects of the different interventions evaluated (that is, sunscreen and beta-carotene). We found no difference in terms of the number of participants developing BCC (n = 1621; risk ratio (RR) 1.03, 95% confidence interval (CI) 0.74 to 1.43) or cSCC (n = 1621; RR 0.88, 95% CI 0.50 to 1.54) when comparing daily application of sunscreen with discretionary use, even when analyses were restricted to groups without beta-carotene supplementation. This evidence was of low quality, which means that there is some certainty that future studies may alter our confidence in this evidence.We reported adverse events in a narrative way and included skin irritation or contact allergy.We identified no studies that evaluated other sun protection measures, such as the use of sun-protective clothing, sunglasses, or hats, or seeking the shade when outdoors. AUTHORS' CONCLUSIONS: In this review, we assessed the effect of solar protection in preventing the occurrence of new cases of keratinocyte cancer. We only found one study that was suitable for inclusion. This was a study of sunscreens, so we were unable to assess any other forms of sun protection. The study addressed our prespecified primary outcomes, but not most of our secondary outcomes. We were unable to demonstrate from the available evidence whether sunscreen was effective for the prevention of basal cell carcinoma (BCC) or cutaneous squamous cell carcinoma (cSCC).Our certainty in the evidence was low because there was a lack of histopathological confirmation of BCC or cSCC in a significant percentage of cases. Amongst other sources of bias, it was not clear whether the study authors had assessed any interaction effects between the sunscreen and beta-carotene interventions. We think that further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.

Consumo de alcohol y otras sustancias, un problema en estudiantes universitarios de salud / Consumption of alcohol and other substances, a health problem in college students / O consumo de álcool e outras substâncias, um problema de saúde em estudantes universitários

Objetivo: caracterizar el consumo de alcohol y otras sustancias, los motivos para consumir o no consumir en estudiantes de pregrado de una universidad privada en Santiago de Cali. Materiales y Métodos: estudio descriptivo transversal, con una muestra de 207 estudiantes pertenecientes a dos programas de salud de una universidad privada, estuvo integrada por estudiantes entre los 14 y 49 años de edad, media de 23 años, seleccionados aleatoriamente por muestreo estratificado proporcional. Se utilizó un cuestionario de auto reporte Alcohol Use Disorders Identification Test y preguntas sobre los motivos de consumo de sustancias legales e ilegales. Se realizó análisis univariado y estimadores con intervalos de confianza, en relación con otras variables se calculó prueba de X 2 utilizando Epi Info 7. Resultados: el consumo en el último año para sustancias legales como alcohol es de 76.8% (IC 95%: 70.5-82.4) para cigarrillo de 15% (IC 95%: 10.4-20.6). Para sustancias ilegales como la marihuana un 1% (IC 95%: 0.1-3.4). Entre las razones para el consumo los participantes manifiestan que los hace sentir bien en un 69.3% (IC 95%: 60.6-75.2) Conclusiones: entre los universitarios del área de la salud, el consumo de sustanciales legales es semejante al de la población general. La elaboración de planes de intervención para prevenir el consumo de drogas legales e ilegales, es una tarea que debe asumir la academia en su labor educativa y de proyección social de manera permanente.

Objective: to characterize the consumption of alcohol and other substances, and the reasons to consume or not consume in undergraduate students from a private university in Santiago de Cali. Materials and Methods: cross-sectional descriptive study with a sample of 207 students from two health programs at a private university. The study comprised students between 14 and 49 years old, average 23 years, randomly selected by proportional stratified sampling. A self-evaluating questionnaire Alcohol Use Disorders Identification Test and questions about the reasons for use of legal and illegal substances were used. Univariate and estimators analysis with confidence intervals were conducted in conjunction with other variables, the X2 test was calculated using Epi Info 7. Results: consumption in the last year for legal substances such as alcohol is 76.8% (95% CI: 70.5 -82.4) for cigarettes of 15% (95% CI 10.4-20.6). For illegal substances like marijuana 1% (95% CI: 0.1-3.4). Among the reasons for consumption the participants that state that it makes them feel good were 69.3% (95% CI 60.6-75.2) Conclusions: among college students health concerns concerning legal substantial consumption is similar to that of the general population. Developing contingency plans to prevent the use of legal and illegal drugs, it is a task that the academy must assume in its permanent educational and social outreach.
