Effects of Computerized Decision Support Systems on Practitioner Performance and Patient Outcomes: Systematic Review (Preprint)
Authors: Kruse Clemens Scott , Ehrbar Nolan
Published: December 2019

BACKGROUND

Computerized decision support systems (CDSSs) are software programs that support the decision making of practitioners and other staff. Other reviews have analyzed the relationship between CDSSs, practitioner performance, and patient outcomes. These reviews reported positive practitioner performance in over half the articles analyzed, but very little information was found for patient outcomes.

OBJECTIVE

The purpose of this review was to analyze the relationship between CDSSs, practitioner performance, and patient medical outcomes. PubMed, CINAHL, Embase, Web of Science, and Cochrane databases were queried.

METHODS

Articles were chosen based on year published (last 10 years), high quality, peer-reviewed sources, and discussion of the relationship between the use of CDSS as an intervention and links to practitioner performance or patient outcomes. Reviewers used an Excel spreadsheet (Microsoft Corporation) to collect information on the relationship between CDSSs and practitioner performance or patient outcomes. Reviewers also collected observations of participants, intervention, comparison with control group, outcomes, and study design (PICOS) along with those showing implicit bias. Articles were analyzed by multiple reviewers following the Kruse protocol for systematic reviews. Data were organized into multiple tables for analysis and reporting.

RESULTS

Themes were identified for both practitioner performance (n=38) and medical outcomes (n=36). A total of 66% (25/38) of articles had occurrences of positive practitioner performance, 13% (5/38) found no difference in practitioner performance, and 21% (8/38) did not report or discuss practitioner performance. Zero articles reported negative practitioner performance. A total of 61% (22/36) of articles had occurrences of positive patient medical outcomes, 8% (3/36) found no statistically significant difference in medical outcomes between intervention and control groups, and 31% (11/36) did not report or discuss medical outcomes. Zero articles found negative patient medical outcomes attributed to using CDSSs.

CONCLUSIONS

Results of this review are commensurate with previous reviews with similar objectives, but unlike these reviews we found a high level of reporting of positive effects on patient medical outcomes.

Published: December 2019

Pseudomonas aeruginosa (P. aeruginosa) is an opportunistic bacterium, which could aggressively infect immunocompromised patients and thus, cause high mortality rate. In addition, P. aeruginosa in oropharynx could be aspirated and cause ventilator associated pneumonia. Royal jelly is one of bee’s products that has been used for therapeutic needs including antibacteria. Adherence factor of P. aeruginosa were flagelum, pili and lectin. The aim of the study was to determine the effect of royal jelly to P. aeruginosa adhesion. Suspension of P. aeruginosa (ATCC® 27853) was incubated at 37 °C for 18 h. Treatment groups were exposed to royal jelly with several concentrations, 2%, 4%, 6%; while distilled water was being used as negative control. Bacterial adhesion test was determined using spectrophotometer λ = 600 nm to measure optical density values of adhered bacterial suspension in tubes. The result of one-way ANOVA showed significant differences (p<0.05) of optical density values among groups indicating that royal jelly affected the bacterial adhesion. LSD results showed significant difference of optical density values between 2%, 4%, and 6% royal jelly compared to distilled water. Six percent of royal jelly had the least optical density value compared to the other groups. In conclusion, royal jelly has the ability to decrease adhesion of P. aeruginosa. Six percent of royal jelly has better ability to decrease adhesion of P. aeruginosa than other concentrations.

Published: December 2019

Exclusive breastfeeding during the first six months of life is extremely important for the development of the dentocraniofacial structure, occlusion, breathing and swallowing during childhood. The prevalence severity rate of malocclusion in children who were breastfed is lower than those who were bottle-fed. The aim of this study is to evaluate the associations of infant feeding patterns on the deciduous second molar relationship in preschool aged children (3-5 years old children) of selected preschools in and around Medan Selayang. This study used analytic cross-sectional study design as the research method. The sampling was carried out by purposive sampling technique. This study involved  130 children aged 3-5 years as the sample, who consisted of two groups, the exclusively breastfed group and the bottle-fed group with the inclusion criteria of the children having a good oral and dental health. The result is statistically analyzed using Chi Square with a significance level of p<0.05. There was a significant difference between children who were breastfed and those who were bottle-fed. Children who were breastfed mostly had mesial step (55, 4%), followed by distal step(27.7%) and flush (16.9%), while those children who were bottle-fed mostly had distal step (46.2%), flush (33.8%), and mesial steps (20%). Based on Chi Square test, it is shown that there is a significant relationship between infant feeding patterns to primary molar relationships (p<0.001).

Authors: Roura Álvarez Lisette , Hernández de Lara Odlanyer
Published: December 2019

La relevancia histórica de Guanabacoa, poblado que surge como reducción de indios en La Habana y donde se sucedieron importantes procesos sociohistóricos, contrasta con la exigüidad de intervenciones arqueológicas practicadas, y la necesidad de dilucidar cuestiones relativas al emplazamiento de la primera iglesia y cementerio, área que constituyó el núcleo urbano a partir del cual se expandió y conformó el actual municipio. En función de esto se implementó el proyecto arqueológico Indios naturales y floridanos en Guanabacoa con el propósito de constatar la ubicación de las mencionadas estructuras, enfocado además en la presencia e interacción de indios naturales y floridanos. El análisis de las abundantes y significativas evidencias arqueológicas halladas constata la continuidad de algunas producciones tradicionales aruacas y la presencia de indios floridanos en el entorno urbano guanabacoense del siglo xviii. Igualmente, ilustran sobre el comercio, la producción de azúcar, la religión, el divertimento, la construcción de inmuebles, la alimentación, el procesamiento de alimentos y actividades que incluían elementos vinculados con la apariencia personal. Los resultados obtenidos en la primera etapa de investigación arqueológica evidencian la necesidad de continuar la implementación del proyecto en el área seleccionada.

Authors: Mamieva Z. A. , Poluektova E. A. , Shifrin O. S.
Published: December 2019

Aim. To review data on the efficiency and safety of using Ustekinumab in patients with Crohn’s disease.

Key findings. Ustekinumab is a fully human monoclonal antibody of the IgG1k class to the p40 subunit of IL-12 and IL-23. The drug interrupts the cascade of humoral and cellular reactions leading to transmural inflammation of the intestinal wall by blocking the interaction of the p40 subunit with the IL-12Rβ1 chain on the surface of T-lymphocytes and NK cells. A number of placebo-controlled studies have demonstrated the effectiveness of Ustekinumab in the induction and the maintenance of remission in those patients with Crohn’s disease who showed no response to conventional therapy (glucocorticosteroids and immunosuppressants) and therapy with TNF-α antagonists. In addition, the efficiency of Ustekinumab in maintaining a clinical response and clinical remission over two years of therapy has been shown. The drug has a favourable safety profile and a low immunogenicity.

Conclusion. The reviewed studies show Ustekinumab to be an effective and safe drug for the induction and the maintenance of clinical remission in patients with Crohn’s disease.

Aim. To evaluate the efficacy of transarterial chemoembolization in patients with metastases of colorectal cancer in the liver.

Materials and methods. A study aimed at investigating the effect of selective transarterial chemoembolization (TACE) of the hepatic artery on liver metastases in colorectal cancer was conducted at the Oncology Centre of the RZhD Central Clinical Hospital No. 2 named after N.A. Semashko, Moscow. The research basis included data for 10 patients, who had undergone chemoembolization of the hepatic arteries using Biosphere microspheres 50– 100 µm — 25 mg and doxorubicin 50 mg.

Results. Both immediate and long-term results of up to 12 months were evaluated using the RECIST 1.1 scale. A partial response was achieved after 4 TACE treatments in 22.2 % of cases. The stabilization of the oncological process in the liver was observed after 9 TACE treatments in 50 % of cases. Disease progression was noted after 5 procedures in 27.8 % of cases.

Conclusions. Transarterial chemoembolization of metastatic liver lesions in patients with colorectal cancer can be used according to certain indications in specialized centres providing endovascular treatment services.
Do momentum strategies perform better for Islamic stocks than for conventional stocks across market states?
Authors: Tee Lain-Tze , Kew Si-Roei , Low Soo-Wah
Published: December 2019

This study compares the momentum profitability of Islamic and conventional
stocks in Malaysia and examines whether the presence of momentum profits is
market-state dependent. Winner portfolios are shown to outperform loser
portfolios, suggesting that a momentum effect exists in the equity market.
Islamic stocks exhibit stronger momentum than conventional stocks.
Interestingly, although pursuing profit is not the primary goal of Islamic
stock investors, the findings indicate that momentum profits for all Islamic
stock trading strategies are higher than those for conventional stocks. The
profits from momentum strategies for both stocks are market-state dependent.
In all trading strategies, while there are significant positive momentum
profits following market upturns, there is no evidence of profits subsequent
to market downturns. Overall, Islamic stocks yield higher momentum profits
than conventional stocks across market states. These findings are robust to
using various measures of the state of the market. While the presence of
momentum profits is also robust to the inclusion of Fama-French?s (1993)
risk factors, the risk factors are unable to explain momentum profits,
suggesting that the risk-adjusted momentum profits are not due to risk
compensation. Rather, the profitability is evidence of stock mispricing.

A generalization of the zero-divisor graph for modules
Authors: Nozari Katayoun , Payrovi Shiroyeh
Published: December 2019

Let R be a commutative ring and M a Noetherian R-module. The zero-divisor
graph of M, denoted by ?(M), is an undirected simple graph whose vertices
are the elements of ZR(M)\AnnR(M) and two distinct vertices a and b are
adjacent if and only if abM = 0. In this paper, we study diameter and girth
of ?(M). We show that the zero-divisor graph of M has a universal vertex in
ZR(M)\r(AnnR(M)) if and only if R = ?Z2?R? and M = Z2?M?, where M? is an
R?-module. Moreover, we show that if ?(M) is a complete graph, then one of
the following statements is true: (i) AssR(M) = {m1,m2}, where m1,m2 are
maximal ideals of R. (ii) AssR(M) = {p}, where p 2 ? AnnR(M). (iii) AssR(M)
= {p}, where p 3 ? AnnR(M).
Depth-dependence of Degree of Conversion and Microhardness for Dual-cure and Light-cure Composites
Authors: Wang R , Wang Y
Published: December 2019

Clinical Relevance

New dual-cure bulk-fill composites show promise for uniform degree of conversion and microhardness throughout the entire depth of direct restorations.

Objective:

The aim of this study was to evaluate the degree of conversion (DC) through micro-Raman spectroscopy and surface microhardness in Vickers hardness (VHN) of three new dual-cure bulk-fill resin-based composites (RBCs) compared with light-cure bulk-fill and incremental RBCs at two clinically relevant depths and for two light irradiation times.

Methods:

Three commercially available restorative dual-cure bulk-fill RBCs (BulkEZ, HyperFIL, and Injectafil) were evaluated and compared with three light-cure RBCs (Filtek Bulk Fill Flowable, Filtek One Bulk Fill, and incremental Filtek Z250) as controls. Specimens were prepared in two different depths (0.5 mm and 5 mm) and were light irradiated for 20 seconds or 40 seconds. Self-cure was also evaluated for the three dual-cure bulk-fill RBCs. Micro-Raman spectroscopic measurements and VHN tests (n=5) were made after 24 hours of dry storage in the dark at room temperature for all test conditions. Data were analyzed using one-way and two-way analyses of variance (α=0.05).

Results:

All tested RBCs showed significantly higher DC and VHN values at 0.5-mm depth than at 5-mm depth, with the exception of BulkEZ, which showed similar DC and VHN values at two depths. The three dual-cure bulk-fill RBCs showed significantly higher DC than the three light-cure RBCs under the same curing condition. The three dual-cure RBCs showed much smaller differences in VHN values between the two depths than the three light-cure RBCs. Twenty seconds and 40 seconds of light irradiation did not generate significant difference in DC and VHN values for the three dual-cure bulk-fill RBCs at either depth or for the three light-cure RBCs at the 0.5-mm depth; however, 40 seconds of light irradiation generated significantly higher DC and VHN values for One Bulk Fill and Z250 at the 5-mm depth compared with 20 seconds of light irradiation.

Clinical Relevance

Irradiance may decrease as the light-emitting diode (LED) is discharged. Therefore, the LED must be charged carefully to prevent the possibility of influencing the chemical, mechanical, and physical properties of composite resin.

The aim of this study was to evaluate the influence of different light-emitting diode (LED) curing units and battery levels on the chemical, mechanical, and physical properties of composite resins. The irradiance for each cycle from full to completely discharged battery level was evaluated, for five different new cordless LED units: Optilight Color (Gnatus), Bluephase (Ivoclar), Valo (Ultradent), Radii Plus (SDI), and Radii Xpert (SDI). After the irradiance evaluation, composite resin specimens were prepared and light cured, while varying the battery level for each LED unit: high level (HL, 100%), medium level (ML, 50%), and low level (LL, 10%). The degree of conversion, diametral tensile strength, sorption, and solubility were also evaluated. Data were checked for homoscedasticity and submitted to two-way and three-way analysis of variance, depending on the test performed, followed by the Tukey test with a significance level of 95%. A negative correlation was found between irradiance and cycles of light curing, which was checked by the Pearson correlation test. Valo and Radii Xpert were not influenced by the battery level in any test performed. However, different battery levels for some LED units can influence the degree of conversion, diametral tensile strength, sorption, and solubility of composite resins.

A Cross-institutional Study of Instructional Characteristics and Student Outcomes: Are Quality Indicators of Online Courses Able to Predict Student Success?
Authors: Joosten Tanya , Cusatis Rachel , Harness Lindsey
Published: December 2019

A study was conducted to examine instructional characteristics and their relationship to student outcomes in online courses at a 2-year and 4-year higher educational institution.  Instructional characteristics included learner support, course design and organization, content design and delivery, interactivity (student-instructor and student-student), and assessment and evaluation.  A student survey instrument was created that captures student perceptions of the instructional characteristics of their course, their learning, and their satisfaction with the course.  The data collected from the student survey was merged with data from institutional student information systems (e.g., demographics and course grade).This article examines the relationship between these instructional characteristics, sometimes referred to as indicators of online course quality, and their relationship to student outcomes for all students and for underrepresented students.  Significant findings from multiple regression analyses are reported.  Additional analyses were conducted to examine differences among underrepresented students (minorities, first-generation, low-income, students with impairments/disabilities) using MANOVA.  No significant differences are reported.
Instructor Perceptions of Quality Learning in MOOCs They Teach
Authors: Askeroth Jacob H. , Richardson Jennifer C.
Published: December 2019

Discussions regarding the instructional and learning value of Massive Open Online Courses (MOOCs) include the question of whether or not MOOC learners gain much value, if any at all, and has been a continuing debate since MOOCs began.  Skeptics argue that MOOCs lack academic rigor and are superficial, while proponents praise them as addressing important global issues of educational access and affordability, providing pathways to more substantial learning opportunities.  An important viewpoint in this conversation that warrants consideration is that of the professors/instructors who teach MOOCs and how they perceive the quality of learning that takes place in their MOOCs.  In this study, semi-structured qualitative interviews were used with three MOOC instructors and an inductive analysis approach that resulted in the emergence of three main themes.  The findings from this study suggest that instructors do believe that quality learning can take place within a MOOC and is often accomplished through social constructivism and self-regulated learning approaches.  Discussions, dialogues, negotiations, collaborations as well as learners accomplishing their intended goals in the course were all considered to be manifestations of quality learning in a MOOC.  Implications of the findings for additional research and practice are also discussed.
Evaluating Online Learning Orientation Design With a Readiness Scale
Authors: Liu Juhong Christie
Published: December 2019

Student online learning readiness (SOLR) has been identified as being closely associated with the success of learning in online environments. Online learning orientations have also been used as a key intervention to support students. However, the evaluation practice and research of online learning orientation design are limited. This research studied the effects of an orientation course on SOLR, using a multiyear design-based research with a one-group pretest and posttest method as the evaluation measurement. The design and implementation of a self-paced orientation course in Canvas learning management system was detailed as the intervention. A 20-item SOLR questionnaire was selected as the pretest and posttest instrument. After the initial cycles, a sample of 2,590 college students were invited to participate in the 2017 orientation and respond to the pretest and posttest. Because separate consent forms were distributed and collected at the pretest and posttest stages, the researcher was able to use 445 pretest and 624 posttest datasets. The independent samples t-test results indicated statistically significant improvement of SOLR competencies. The exploratory factor analysis results also indicated changes of items associated with the SOLR constructs. The reliability coefficients of all subscales were > .90, with an increase in the reliability of the SOLR instrument as a whole from pretest (a = .92) to posttest (a = .95). Implications for the design and evaluation of online learning orientations and preparing student online learning readiness are discussed toward future design and implementation.

En el presente trabajo de investigación se elaboraron prototipos de sección compuesta con diferentes conectores de cortante, seleccionados en base a las propiedades de cada conector, capacidad de absorción y transferencia de esfuerzos cortantes entre la losa con placa colaborante y la viga de hormigón. Los conectores que fueron parte de esta investigación incluyen tipo arco de varilla corrugada Ø 8mm, tornillo, espigo y tipo estribo, los cuales son contenidos en el sistema para cumplir con funciones como impedir el deslizamiento horizontal y vertical entre losa compuesta y la viga, garantizar la adherencia con el hormigón y brindar la resistencia máxima a la flexión la viga.Estos especímenes fueron sometidos a ensayo de flexión con la finalidad de analizar la influencia de los conectores de corte en la resistencia de la sección compuesta. Cabe recalcar que para que el elemento trabaje como compuesto, éste debe garantizar la correcta interacción entre la placa de acero y la viga de hormigón trabajando como un solo elemento. Para ello se analiza el módulo de rotura de cada espécimen y se compara el momento en el punto de rotura de la sección con el momento teóricamente calculado. Como resultado de la investigación se determinó que el desempeño de los elementos compuestos no solo depende del tipo de conector sino también del número y espaciamiento de los conectores.

Foreign Policy of Alexander I and Nicholas I: Continuity and Difference (1814–1855)
Authors: Vasilenko Sergey Aleksandrovich ,   South Ural State Humanitarian Pedagogical University
Published: December 2019

Emperors in domestic historiography are usually opposed. However, the analysis shows that in the foreign policy of Alexander I and Nicholas I there is a significant continuity. Both emperors sought to defend the alliance of continental monarchs on the basis of the principle of legitimism and traditional values as a strategic goal. This included opposition to the claims of dominance in Europe by Britain, whose policies increasingly relied on liberal values and pragmatic principles. Both emperors also sought to counteract the expansion of revolutionary movements in Europe. As for tactical decisions, Alexander I showed more flexibility and ability to maneuver. This is especially noticeable in his Middle Eastern politics, in which he sought to unite the allies on the platform of the solution proposed by Russia. Nicholas I sought to preserve the system of international relations created by Alexander I, but at the same time showed much less flexibility and diplomacy, refused to notice the changed political realities. The years of his reign became a time of revolutions in Europe, and many European states, starting with Great Britain, began to profess pragmatic principles. Under these conditions, the position of the Russian emperor doomed the country to foreign policy isolation.

The paper studies the historical experience of local formation of a training system of engineering personnel for oil and gas industry in the 1950–1960s in the Tatar ASSR. The authors investigate the mechanisms of training and professional development training of engineering, technical, and managerial personnel of the Soviet period as exemplified by the operation of “Tatneft” enterprise. They identify the specific features of formation of engineering personnel training system in the conditions of development of the oil industry. The authors conclude that the current organization of effective work for personnel training and professional development training in “Tatneft” takes into account scientific and technological advances in the oil industry and specific local production objectives. This fact has allowed to reach target raw materials output and support the development of oil extraction industry complex of Tataria as one of the biggest and technologically advanced in the whole country.

Objectives

Psychotic disorders have large treatment gap in low- and middle-income countries (LMICs) in South-Eastern Europe, where up to 45% of affected people do not receive care for their condition. This study will assess the implementation of a generic psychosocial intervention called DIALOG+ in mental health care services and its effectiveness at improving patients’ clinical and social outcomes.

Methods

This is a protocol for a multi-country, pragmatic, hybrid effectiveness–implementation, cluster-randomised, clinical trial. The trial aims to recruit 80 clinicians and 400 patients across 5 South-Eastern European LMICs: Bosnia and Herzegovina, Kosovo*, Montenegro, Republic of North Macedonia and Serbia. Clusters are clinicians working with patients with psychosis, and each clinician will deliver the intervention to five patients. After patient baseline assessments, clinicians will be randomly assigned to either the DIALOG+ intervention or treatment as usual, with an allocation ratio of 1:1. The intervention will be delivered six times over 12 months during routine clinical meetings. TThe primary outcome measure is the quality of life at 12 months [Manchester Short Assessment of Quality of Life (MANSA)]; the secondary outcomes include mental health symptoms [Brief Psychiatric Rating Scale (BPRS), Clinical Assessment Interview for Negative Symptoms (CAINS), Brief Symptom Inventory (BSI)], satisfaction with services [Client Satisfaction Questionnaire (CSQ-8)] and economic costs at 12 months [based on Client Service Receipt Inventory (CSRI), EQ-5D-5L and Recovering Quality of Life (ReQOL-10)]. The study will assess the intervention fidelity and the experience of clinicians and patients’ about implementing DIALOG+ in real-life mental health care settings. In the health economic assessment, the incremental cost-effectiveness ratio is calculated with effectiveness measured by quality-adjusted life year. Data will also be collected on sustainability and reach to inform guidelines for potentially scaling up and implementing the intervention widely. Conclusion: The study is expected to generate new scientific knowledge on the treatment of people with psychosis in health care systems with limited resources. The learning from LMICs could potentially help other countries to expand the access to care and alleviate the suffering of patients with psychosis and their families.

Vom Ursprung und Ziel der Geschichte
Authors: Jaspers Karl
Published: December 2019

Die These von einer Achsenzeit in der Weltgeschichte
Die zentrale Annahme dieses Buches ist die universalgeschichtliche These von einer Achsenzeit (880–200 v. Chr.) in der Weltgeschichte, in der voneinander unabhängig in China, Indien und dem Abendland strukturell ähnliche kulturelle Revolutionen und Aufbrüche erfolgt sind. Inwieweit diese Aufbrüche für das kulturelle Leben in der Gegenwart weiterhin bedeutsam sind, wird heute in kulturwissenschaftlichen Disziplinen wie der Religions- und Kultursoziologie, der vergleichenden Kulturtheorie, der Theorie der Moderne u.a. neu diskutiert.
Neben der These von der Achsenzeit wird in Vom Ursprung und Ziel der Geschichte u.a. der Stellenwert von Wissenschaft und Technik in der Moderne erörtert; es werden Überlegungen über eine mögliche Welteinheit (im Sinne eines Weltfriedenszustandes) angestellt sowie zeitgeschichtliche Tendenzen in der Politik (z.B. Totalitäts- und Planungsideologien) kritisiert, die im Gegensatz zu Jaspers’ liberalem Ethos der Freiheit und der Humanität stehen.
Progression of peritoneal adenomucinosis to the scrotum: a rare occurrence treated with cytoreductive surgery and hyperthermic chemoperfusion of the scrotum in two patients

Introduction: Disseminated Peritoneal Adenomucinosis (DPAM) is an infrequent presentation of appendiceal cancer. Infrequently, umbilical or inguinal hernias could be the first clinical manifestation of this condition; DPAM extension to the scrotum may be anatomically viable. Treatment with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is the standard of treatment for DPAM. We hypothesize that these same treatment principles, consisting of CRS with hyperthermic chemoperfusion of the scrotum (HCS), could be applied to the scrotal dissemination of DPAM.Methods: We reviewed our Institution’s prospective cancer database and identified two cases of DPAM with extension to the scrotum. Their medical records were examined, and close follow-up was performed. Tumor histopathology and cytoreduction scores were evaluated. Tumor progression was monitored on follow-up by physical examination, tumor markers (CEA, CA 125, CA 19.9) and abdomino-pelvic CT scan.Results: Two patients who previously had CRS/ HIPEC for DPAM were successfully treated with HSC. Both patients are alive and free of disease at 88 and 57 months following initial CRS/HIPEC, and 50 and 32 months following CRS/HCS, respectively. Conclusion: Increased awareness by surgeons to the coexistence of inguinal hernia with peritoneal neoplasm and the need for a surgical repair is raised. CRS/HCS may be employed to treat patients with DPAM extension to the scrotum. Successful outcome is dependent on complete cytoreduction of metastatic tumor.

Objective: The study investigated the effect of supplementation with maltodextrin (CHO) alone or associated to caffeine during exercise in T2DM subjects.Methods: Pilot study, using Eight subjects with T2DM, aged 55±10 years, received CHO (1g/kg) or caffeine (1.5 mg/kg) alone or associated before exercise protocol. The exercise was executed at 40% heart rate (HR) reserve for 40 min, with 10-min recovery. Blood pressure (BP) and perceived exertion scale (Borg) were checked every 2 min. Blood glucose (BG) was checked every 10 min. For statistical analysis, ANOVA test was used and the value was considered statistically significant at p <0.05.Results: The results showed that BP and HR did not change significantly among all treatments. Caffeine promoted a significant reduction in BG of 75 mg/dL (65%, p <0.05) during 40 min of exercise protocol compared to all groups.Conclusion: Supplementation with 1.5 mg/kg of caffeine reduces BG concentration during prolonged exercise in T2DM patients.
The general health social security system and the formation of its human talent

The General Health Social Security System plays a double function in terms of healthcare and formation of its human talent. A historical relationship exists globally between healthcare systems and systems of higher education in health. In Colombia, this relationship has been regulated by the ministries of National Education and Health and Social Protection, not without articulation difficulties. In fact, any situation that affects the healthcare system will necessarily affect the quality of the formation of its human talent in the sector. The country began, with Legislation 100 of 1993, a healthcare insurance model seeking to accomplish universal coverage. Currently, over 90% of the population has some form of insurance and due to pressure from the Constitutional Court the two main regimes have the same benefits plan, although with different values of the capitation payment unit (CPU). Although it has been recognized that the vulnerable population now has more access to healthcare services and that currently a quality assurance system is in place, it is also true that unacceptable inequities exist according to the people’s payment capacity; we have lost the vision of public health, which must organize the system as a whole and there is no effective intervention of the healthcare social determinants.

Introduction. The surgical management of cholesteatoma. You can opt for a closed technique (mastoidectomy simple) or open surgery (radical mastoidectomy). The open mastoidectomy with reconstruction of the posterior wall of the middle ear reconstruction in one surgery combines the advantages of both techniques as adequate surgical exposure, eradication of cholesteatoma and anatomical reconstruction of the middle ear structures. Objective. To evaluate the surgical results in the management of cholesteatoma with the technique of open mastoidectomy with reconstruction of the posterior wall and the middle ear in one surgery. Methods. Prospective analytical observational study conducted between 2009-2012 with patients undergoing this surgical technique in the Hospital Universitario del Valle, performing preoperative clinical monitoring and quarterly postoperative tomography and previous assessments of hearing and pre -and postoperative audiometry. Results. 45 patients were studied. Mean Postoperative follow-up was 28 months. Surgical success was achieved in 93.3% of patients as measured by clinical and radiological follow. Hearing preservation was found after reconstruction of the hearing mechanism, based on measured audiometry auditory tone average (PTA) by the statistical test for paired samples between preoperative and postoperative PTA. (95% CI -1.47 to 12.15). Residual cholesteatoma was presented in 6.6%, three to four times lower than that reported in the literature. Conclusions. This type of surgery can be considered a successful technique in the treatment of cholesteatoma in selected cases.
