RESUMEN Introducción En México, esta indagación hasta donde se tiene conocimiento representa el primer trabajo multicéntrico que estudia el grado de desarrollo de la aptitud clínica en cuatro Unidades de medicina familiar del Sector Salud. Por consiguiente, la interrogante de investigación es ¿Cuál es el grado de desarrollo de la aptitud clínica en tres instituciones de salud?. Este estudio proveerá conocimientos que permitirán emprender investigaciones en las cuales se ensayen estrategias educativas que propicien el desarrollo de esta aptitud. Objetivo Determinar el grado de desarrollo de la aptitud clínica en residentes de medicina familiar de cuatro sedes académicas. Método Diseño prospectivo, transversal, observacional y multicéntrico. Se estudió toda la matrícula del ciclo académico 2019-2020 con consentimiento informado. Se construyó un instrumento que evaluó la variable “aptitud clínica” mediante ocho indicadores y 182 ítems; la validez conceptual, de contenido y confiabilidad se valoró por cinco médicos familiares con experiencia docente y en investigación educativa. Resultados De las cuatro sedes, las calificaciones globales más altas en los indicadores fueron alcanzadas por los R1 de la Unidad de Medicina Familiar # 20 del Instituto Mexicano del Seguro Social (UMF20 IMSS), R2 y R3 del Hospital General de Zona # 1 (HGZMF1 IMSS). Los R1 de la UMF20 alcanzaron los más altos puntajes en 3/8 indicadores. Los R2 y R3 del HGZMF1 lograron las más altas puntuaciones en 2/8 indicadores. Se estimaron diferencias entre R1 (n=46), entre R2 (n=47) y entre R3 (n=40) de las cuatro sedes por indicador y no se encontraron diferencias estadísticas significativas en ningún caso. Conclusiones El grado de desarrollo de la aptitud clínica se puede considerar de nivel medio en las cuatro sedes académicas. Esto en parte se puede explicar a que el instrumento exploró situaciones clínicas problematizadas, que exigieron del residente la reflexión crítica de su experiencia clínica antecedente.

ABSTRACT Introduction In Mexico, this inquiry to the best of our knowledge represents the first multicenter work that studies the degree of development of clinical aptitude in four Family Medicine Units of the Health Sector. Therefore, the research question is : What is the degree of development of clinical aptitude in three health institutions? This study will provide knowledge that will allow undertaking researches in which educational strategies that propitiate the development of this aptitude are tested. Objective To determine the degree of development of clinical aptitude in family medicine residents from four academic sites. Method Prospective, cross-sectional, observational and multicenter design. The entire enrollment of the 2019-2020 academic year was studied with informed consent. An instrument was constructed that assessed the variable "clinical aptitude" by means of eight indicators and 182 items; conceptual, content and reliability validity was assessed by five family physicians with teaching and educational research experience. Results Of the four sites, the highest overall scores on the indicators were achieved by the R1 of the Family Medicine Unit # 20 of the Mexican Social Security Institute (UMF20 IMSS), R2 and R3 of the General Zone Hospital # 1 (HGZMF1 IMSS). UMF20 R1s achieved the highest scores on 3/8 indicators. The R2s and R3s of HGZMF1 achieved the highest scores on 2/8 indicators. Differences were estimated between R1s (n=46), between R2s (n=47) and between R3s (n=40) of the four sites by indicator and no significant statistical differences were found in any case. Conclusions The degree of development of clinical aptitude can be considered medium level in the four academic sites. This can be partly explained by the fact that the instrument explored problematic clinical situations, which required the resident to reflect critically on his previous clinical experience.

ABSTRACT Introduction: Adherence to non-pharmacological treatment of diabetes mellitus is a key factor in avoiding or delaying the complications of this disease. Treatment compliance depends on multiple factors. Objective: To evaluate adherence to dietary hygienic treatment in patients with diabetes mellitus, especially nutrition and physical activity. Demographic variables and the presence of arterial hypertension were also measured. Methodology: An interview was conducted with adult male and female patients, carriers of diabetes mellitus, residing in the Sajonia neighborhood of Asunción, Paraguay, between May and October 2022. Demographic and clinical variables were measured. Adherence was determined with the Caro Bautista questionnaire, which consists of seven questions that evaluate the therapeutic practices of patients in the last week. The study was approved by the Ethics Committee of the Faculty of Medicine of the Universidad Privada del Este, Paraguay. Results: Two hundred fifty-seven people diagnosed with diabetes mellitus were interviewed, with a predominance of females (61.4%), 73.9% reported having their own income and 49% also suffered from arterial hypertension. The questionnaire detected that 20.1% followed a healthy diet all week, 15.5% performed daily physical exercises, and 14.3% performed capillary blood monitoring regularly. Conclusion: Between 10 and 22% of patients with diabetes mellitus perform adequate diet and exercise, as well as glycemia monitoring according to the recommendations of their physicians.

RESUMEN Introducción: la adherencia al tratamiento no farmacológico de la diabetes mellitus es un factor clave para evitar o retrasar las complicaciones de esta enfermedad. El cumplimento terapéutico depende de múltiples factores. Objetivo: evaluar la adherencia al tratamiento higiénico dietético en pacientes con diabetes mellitus, sobre todo la nutricional y la actividad física. Se midieron además las variables demográficas y presencia de hipertensión arterial. Metodología: se realizó una entrevista a pacientes adultos de ambos sexos, portadores de diabetes mellitus, que residen en el barrio Sajonia de Asunción, Paraguay, entre mayo y octubre del 2022. Se midieron variables demográficas y clínicas. La adherencia se determinó con el cuestionario de Caro Bautista que consta de 7 preguntas que evalúan las prácticas terapéuticas de los pacientes en la última semana. El estudio contó con la aprobación del Comité de ética de la Facultad de Medicina de la Universidad Privada del Este, Paraguay. Resultados: fueron entrevistados 257 personas con el diagnóstico de diabetes mellitus, con predominio del sexo femenino (61,4%), 73,9% refería tener ingresos propios y 49% padecía también de hipertensión arterial. El cuestionario detectó que 20,1% seguía una dieta saludable toda la semana, 15,5% realizaba ejercicios físicos diariamente y 14,3% realizaba los monitoreos de sangre capilar regularmente. Conclusión: entre 10 y 22% de los pacientes con diabetes mellitus realiza dieta y ejercicios adecuados, así como monitoreo de la glucemia según las recomendaciones de sus médicos.

Abstract To establish the cut-off point between normal and impaired fasting glycemia (IFG) is extremely important for the purposes of considering a patient at risk both of progressing to more advanced stages of the disease and of suffering micro- and macroangiopathic complications. Since 2006, the Argentine Diabetes Society (ADS), based on the evidence considered at that time, established the lower limit of IFG at 110 mg/d, laterduring the year 2022, The Board of Directors of the ADS vened a group of experts in order to assess whether this recommendation should be maintained or, like other prestigious scientific societies, adopt 100 mg/dl for this purpose. This Opinions and Recommendations document contains therationale for which the SAD will adopt, from now on, 100 mg/dlas the lower limit of the IFG, based on the new scientific edence that shows that from this cut-off point it produces increase in progression to diabetes and both macro and microangiopathic complications.

Resumen Establecer el punto de corte entre la glucemia en ayunas normal y la alterada resulta de suma importancia a los efectos de considerar a un paciente en riesgo, tanto de progresar a estdos más avanzados de la enfermedad como de sufrir complicaciones micro y macroangiopáticas. Desde 2006 la Sociedad Argentina de Diabetes (SAD), sobre la base de la evidencia considerada en ese momento, estableció el límite inferior de la glucemia alterada en ayunas (GAA) en 110 mg/dl; posteriormente, durante 2022, la Comisión Directiva de la SAD convocó a un grupo de expertos con el objeto de evaluar si esta recomendación debía mantenerse o, al igual que otras sociedades científicas de prestigio, adoptar a tal efecto 100 mg/dl. En este documento de Opiniones y Recomendaciones se encuentran los fundamentos por los cuales la SAD adoptará, de ahora en más, 100 mg/dl como límite inferior de la GAA, en base a las nuevas evidencias científicas que muestran que desde este punto de corte se produce un aumento en la progresión a la diabetes mellitus y de las complicaciones tanto macro como microangiopáticas.

Abstract Factor X deficiency ranks among the rarest coagulopathies and has a variable presentation spectrum. We intend to present a proposal for anesthesia protocol for individuals with the coagulopathy. The excision of an ovarian neoplasm was proposed for a 26-year-old, female, ASA II patient, with congenital Factor X deficiency. Physical examination and lab tests were normal, except for Prothrombin Time (PT) 22.1s (VR: 8-14s), International Normalized Ratio (INR) 1.99 (VR: 0.8-1.2) and Activated Partial Thromboplastin Time (aPTT) 41.4s (VR: 25-37s). We concluded that a history of bleeding should always be investigated, along with a pre-anesthetic coagulation study.

Abstract The objective of this work was to evaluate the postharvest behavior of the fruit of mango cv. Ataulfo in a state of physiological maturity in response to infection induced by Colletotrichum siamense and Colletotrichum asianum. Mangoes were inoculated with C. siamense and C. asianum and stored for 10 days at 28 °C and RH of 85-90%. The virulence of Colletotrichum spp. was evaluated in the fruits. And its effect on the variables of physical, chemical quality and respiration. At 10 days of storage, C. siamense showed greater virulence than C. asianum in mango fruits, with some differences in internal color between inoculated fruits and controls. The fruits inoculated with C. asianum had greater respiratory activity and lower texture with respect to the control. The physical and chemical quality variables in the fruits showed significant differences with respect to storage time, but not due to the presence of the fungus. The infection of the mangoes caused by the two species of Colletotrichum manifested as necrotic spots in the infected area of the fruits, affecting the appearance and visual quality.

Resumen El objetivo de este trabajo fue evaluar el comportamiento postcosecha del fruto de mango cv Ataulfo en estado de madurez fisiológica como respuesta a la infección inducida por Colletotrichum siamense y Colletotrichum asianum. Se inocularon mangos con C. siamense y C. asianum y se almacenaron durante 10 días a 28 °C y HR de 85-90%. En los frutos se evaluó la virulencia de Colletotrichum spp. Y su efecto en las variables de calidad físicas, químicas y la respiración. A los 10 días de almacenamiento, C. siamense mostró mayor virulencia que C. asianum en los frutos de mango, con algunas diferencias en el color interno entre los frutos inoculados y los testigos. Los frutos inoculados con C. asianum presentaron mayor actividad respiratoria y menor textura con respecto al testigo. Las variables de calidad físicas y químicas en los frutos mostraron diferencias significativas con respecto al tiempo de almacenamiento, pero no por la presencia del hongo. La infección de los mangos causada por las dos especies de Colletotrichum se manifestó como manchas necróticas en la zona infectada de los frutos, afectando la apariencia y la calidad visual.

Resumen: Introducción: La coccidioidomicosis es una micosis exclusiva del continente americano, siendo endémica en el suroeste de Estados Unidos y noroeste de México. La aspergilosis es una micosis oportunista causada por el hongo saprófito del suelo Aspergillus spp. Los principales factores de riesgo que favorecen la presencia de estas micosis son el daño pulmonar estructural y el compromiso inmunológico. Caso clínico: Se presenta un caso de coinfección por Aspergillus spp. y Coccidioides spp. en un paciente con antecedentes de tuberculosis pulmonar y diabetes mellitus. El examen de esputo informó el aislamiento simultáneo de Coccidioides spp. y Aspergillus spp. Conclusiones: En pacientes con síntomas respiratorios y antecedente de tuberculosis y secuelas fibrocavitarias es fundamental descartar inicialmente una recidiva tuberculosa, pero al mismo tiempo investigar la presencia de hongos endémicos y oportunistas.

Abstract: Introduction: Coccidioidomycosis is exclusive to the American continent, being endemic in the southwestern United States and northwestern Mexico. Aspergillosis is an opportunistic mycosis caused by the saprophytic soil fungus Aspergillus spp. The main risk factors that favor the presence of these mycoses are structural lung damage and immunocompromise. Clinical case: We present a case of coinfection by Aspergillus spp. and Coccidioides spp. in a patient with a history of pulmonary tuberculosis and diabetes mellitus. Sputum examination reported the simultaneous isolation of Coccidioides spp. and Aspergillus spp. Conclusions: In patients with respiratory symptoms and a history of tuberculosis and fibrocavitary sequelae, it is essential to rule out initially a tuberculosis relapse, but at the same time, investigate the presence of endemic and opportunistic fungi.

Abstract A narrative review that raises a reflection about the role of hyperbaric oxygenation in the recovery of monoxide carbon (CO) poisoning is carried out. A description of the relationship of the pressure of hyperbaric oxygen therapy (HBOT), oxygen dosage, and the delay in its implementation was done. Nine cases of intoxications treated with HBOT at 1.45 ATA due to lack of access to high-pressure HBOT were presented. While additional research is necessary, we suggest that this therapeutic modality at 1.45 ATA (Absolute Atmospheres) should be chosen instead of normobaric oxygen therapy for CO poisoning, and considered when high pressure facilities are not available at reasonable distances.

Resumen Se realiza una revisión narrativa que plantea una reflexión acerca del rol de la oxigenación hiperbárica en la recuperación de los intoxicados con monóxido de carbono (ICO). La relación presión de tratamiento de oxigenación hiperbárica (TOHB), o sea dosis de oxígeno, y demora en su implementación son descriptas en esta revisión. Se presentan 9 casos de pacientes con ICO tratados con TOHB a 1,45 ATA (Atmósferas absolutas) por falta de acceso a TOHB de alta presión. Si bien es necesario investigación adicional, sugerimos que esta modalidad terapéutica a 1,45 ATA para ICO debe ser elegida frente al oxígeno normobárico, y considerada cuando las instalaciones de alta presión no están disponibles a distancias razonables.

Objective: To evaluate the presence of flu-like syndrome suggestive of COVID-19 in men who have sex with men (MSM) and engaged in casual sex during a period of social isolation. Method: National epidemiological survey, applied in April and May 2020, by adaptation of Respondent Drive Sampling. Results: 1,337 MSM participated in the survey, of which 514 (38.4%) had fever associated with another sign or symptom of flu-like syndrome. Social, demographic characteristics, sexual practices and activities during the period of social isolation were statistically associated with the presence of flu-like syndrome. There was a statistical difference (p lt; 0.001) in the average of partners between those who had signs and symptoms of flu-like syndrome (3.5) and those who did not (1.7). Conclusion: Evidence of signs and symptoms indicative of flu-like syndrome suggestive of COVID 19 in Brazilian MSM who were involved in casual sex during the period of social isolation.

Abstract Introduction: In the Educational Research and Teacher Training Centers (CIEFD´s) IMSS, teachers who serve as tutors of the residents are trained. There is a concern about how to develop critical reading and which educational strategy to implement. Objective: To determine the relationship between the participation in the classroom of the teachers who attend the courses in the CIEFD's and the development of the aptitude for critical reading of educational research reports. Method: An intervention and multicentric study was carried out, with teachers enrolled in the courses about teaching methodology (DMDN), 1 and 2 levels (n = 46 and n = 29, respectively) of the six CIEFD's from March to August 2017. To evaluate the student participation in the classroom an instrument was designed. This instrument includes five categories and 18 indicators. Interobserver variability was estimated with a concordance test (weighted Kappa 0.80). The aptitude for critical reading was evaluated using an instrument with three indicators and 140 items. Its conceptual and content validity and reliability was assessed by experts in educational research with teaching experience. The DMDN 1 and 2 lasted 360 and 288 hours respectively, and were developed with the promoting participation educational strategy. The measuring instruments were applied twice (initial and final measurements). The initial measurement to assess the participation of the student in the classroom was made at the middle of both courses. Results: Significant statistical associations were observed in the DMDN 1 of four CIEFD's. Conclusions: From the analysis of the results, we can infer that some of the theoretical proposals of participatory education were recreated. In some Centers, the strengthening of participation with this educational intervention is related to the development of critical reading of educational research reports.

Abstract: Introduction: Timely initiation of treatment is crucial for program management in countries with a high burden of multidrug-resistant tuberculosis (MDR-TB). The delay in the initiation of the treatment allows the transmission in the community and the appearance of TB-MDR cases. Material and methods: Retrospective review of the files of the Tuberculosis Clinic of the Tijuana General Hospital, including all cases with a diagnosis of tuberculosis with rifampicin resistance (RR-TB) or MDR-TB, during the period between 2006-2019. The interval (in days) between the regimen prescription and the start of treatment was determined. Results: 52 patients were included. The delay in the initiation of treatment after having recommended a treatment regimen for TB-RR /MDR was 115.6 ± 109.2 days (3.8 months) with a median of 97.5 days. The delay in patients who were cured was 113.4 days versus 155.0 days for patients who died (p = 0.83). Conclusions: The time interval between prescription of treatment of an RR/MDR-TB case and the start of treatment (115 days) is unacceptably long. The network for MDR-TB care would be strengthened with the decentralization of stocks of second-line anti-tuberculosis drugs.

Resumen: Introducción: El inicio oportuno del tratamiento es crucial para la gestión programática en los países con una alta carga de tuberculosis multidrogorresistente (TB-MDR). El retraso en el inicio del tratamiento permite la transmisión en la comunidad y la aparición de casos de tuberculosis multidrogorresistente. Material y métodos: Se analizó el archivo de la Clínica y Laboratorio de Tuberculosis del Hospital General Tijuana y se incluyeron todos los casos con diagnóstico de tuberculosis con resistencia a rifampicina o multidrogorresistente durante el período comprendido entre el año 2006-2019. Se determinó el intervalo en días entre el dictamen clínico y el inicio de tratamiento. Resultados: Se incluyeron 52 pacientes. El retraso en el inicio de tratamiento después de haber dictaminado el caso como TB-RR/MDR fue de 115.6 ± 109.2 días (3.8 meses) con una mediana de 97.5 días. El retraso en los pacientes que egresaron por curación fue de 113.4 días versus 155.0 para los pacientes que fallecieron (p = 0.83). Conclusiones: El intervalo de tiempo entre el dictamen de un caso de tuberculosis resistente a rifampicina/multidrogorresistente y el inicio del tratamiento (115 días) es inaceptablemente prolongado. La red para la atención de la tuberculosis multidrogorresistente se vería fortalecida con la descentralización de las existencias de fármacos antituberculosis de segunda línea.

Second-line injectable drugs (kanamycin, amikacin and capreomycin) have been an integral part of the multidrug-resistant tuberculosis (MDR-TB) treatment regimen for decades, despite their known association with renal failure and ototoxicity. Unfortunately, there are many countries that haven’t included new or reused drugs in their treatment regimens for MDR-TB and still depend on second-line injectable drugs (SLIDs) in order to have a sufficient amount of effective drugs in their regimens. Our purpose is to show the frequency and severity of the ototoxicity associated with the use of SLIDs only detected initially by means of an audiometry. We conducted a retrospective analysis including all the patients who received treatment regimens with SLIDs from 2010 to 2017 in a tuberculosis clinic in Mexico. 47 patients who received SLIDs (amikacin, kanamycin, capreomycin) were included in the analysis. The mean age was 40.3 ± 16.4 years. Thirty one patients (63.3%) had previously received TB treatment in the past. The most commonly used SLID was amikacin in 33 cases (67.3%), followed by capreomycin in 14 cases (28.6%). Twenty seven patients (55.1%) developed significant hearing loss (> 40 dB), and 13 patients (26.5%) developed severe or profound hearing loss (> 70 dB). Severe hearing loss is a common, irreversible and now unnecessary complication of the MDR/RR-TB (multidrug- and rifampicin-resistant tuberculosis) treatment, since the SLIDs may and shall be substituted by new and reused, more effective and far less toxic drugs.
