Actitudes de los médicos familiares mexicanos sobre el uso de placebos en la práctica clínica.

INTRODUCTION: The use of placebo has spread in clinical practice despite being controversial. In Mexico, the practice of family medicine is predominantly institutional and works with an essential medications list. OBJECTIVE: To determine the frequency and family doctor attitude regarding the use of placebos in clinical practice. METHOD: Cross-sectional, observational, multicenter study of 307 family doctors with active practice in 27 states of the Mexican Republic. A questionnaire was used with sociodemographic data and consensus-developed questions about frequency of use and attitudes. For analysis, the square-chi test was used. RESULTS: 75% used placebos (95% CI=69.7-79.4%); 122 (39.7%) used pure placebos, mainly water (p < 0.05), and 220 (71.6%), impure placebos, mainly vitamins and laboratory tests. They were used more in patients with medically unexplained physical symptoms (178, 45.5%), including 122 (31.2%) "healthy worried" patients, or who had chronic conditions (40, 12.5%). Reasons for prescription: 249 (81%) for the psychological effect, when they showed benefit (176, 57%), even when it implied deceiving (78, 25%) or insufficient evidence of efficacy (57, 19%). The main reason was because of patient insistence. CONCLUSIONS: More impure placebos were used, mainly in healthy worried patients and in those with chronic conditions.

INTRODUCCIÓN: El uso de placebo se ha extendido en la práctica a pesar de ser polémico. En México, la práctica de medicina familiar es predominante institucional y trabaja con un cuadro básico de medicamentos. OBJETIVO: Determinar la frecuencia y actitud del médico familiar en la utilización de placebos en la práctica clínica. MÉTODO: Estudio transversal, observacional, multicéntrico, en 307 médicos familiares con práctica activa, en 27 estados de la República Mexicana. Se usó cuestionario con datos sociodemográficos, preguntas sobre frecuencia de uso y actitudes elaboradas por consenso. Se analizó con chi cuadrada. RESULTADOS: 75 % utilizó placebos (IC 95 % = 69.7-79.4 %); 122 (39.7 %) placebos puros, principalmente agua (p < 0.05), y 220 (71.6 %) placebos impuros, principalmente vitaminas y exámenes de laboratorio. Los usaron más en pacientes con síntomas físicos no explicados médicamente (178, 45.5 %), incluidos 122 (31.2 %) pacientes "sanos preocupados" o con padecimientos crónicos (40, 12.5 %). Motivos de prescripción: 249 (81 %) por el efecto psicológico, cuando demostraron beneficio (176, 57 %), aun cuando implicara engaño (78, 25 %) o evidencia de eficacia insuficiente (57, 19 %). El principal motivo fue por insistencia del paciente. CONCLUSIONES: Se utilizaron más placebos impuros, principalmente en pacientes sanos preocupados y en aquellos con padecimientos crónicos.

Stages of Change for Mammography Among Mexican Women and a Decisional Balance Comparison Across Countries.

An analysis of the adoption of secondary preventive behaviors is significant in regions with disparities in mammography use and breast cancer survival. Therefore, we determined the cognitive factors and the degree to which they differentiate stages of change in mammography among Mexican women. We also compared the decisional balance performance at Mexico, Switzerland, South Korea, and the USA. A cross-sectional study was designed for women in the stages of precontemplation (n = 240), contemplation (n = 243), action (n = 205), maintenance (n = 311), and relapse (n = 348). We only considered those ≥40 years with no cancer history. We measured the pros, cons, and self-efficacy, among other components. The decisional balance was estimated, and the result was transformed into T-scores. Odds ratios (OR) and 95% confidence intervals (CI) were estimated with multinomial logistic regression using precontemplation as the reference group. The decisional balance distinguished stages partially: in contemplation, the OR was 1.26 (95%CI 1.08, 1.47) and in maintenance, 1.34 (95%CI 1.13, 1.59); in action and relapse, the statistical significance was marginal (p < 0.10). The decisional balance T-score performance registered variations among countries. Additionally, the effect of self-efficacy progressively ascended from contemplation to action and maintenance (OR = 1.29 [95%CI 1.05, 1.58], 1.53 [95%CI 1.20, 1.96], and 2.48 [95%CI 1.82, 3.39], respectively). Furthermore, risk perception and severity did not have an effect on stages of change among Mexican women. Recognition of what provokes action in a population is a key factor in the efficacy of screening programs. Variations among countries highlight the necessity for importance of investigating cognitive determinants for mammography in specific areas.

Absence of antibodies against Bordetella pertussis in pregnant women and newborns in the state of Nuevo Leon.

AIMS: To assess placental transfer of antibodies to the child at birth and at 2 months of age. MATERIALS AND METHODS: For the quantification of anti-PT IgG antibodies, we used an indirect enzyme-linked immunosorbent assay standardized by The National Institute of Epidemiologic Diagnosis and Reference (InDRE). Samples were considered negative from 0 to 48 IU/mL, indeterminate from 49 to 93 IU/mL and positive at ≥94 IU/mL. We performed a cross-sectional assessment of anti-PT IgG antibody levels in the mother, umbilical cord, and child. RESULTS: There was a higher concentration of IgG anti-TP in the umbilical cord (4.3%) and in the mother (1.4%), but a total absence was observed in the child (0%). CONCLUSION: The vulnerability of children to Bordetella pertussis shows the need to implement effective immunization strategies, whether actively, in the child, or passively through the mother, adolescents, and adults who are in contact with the child.

[Impact of a psychosocial intervention in caregiver burden of children with cerebral palsy]. / Impacto de una intervención psicosocial en la carga del cuidador de niños con parálisis cerebral.

OBJECTIVE: To demonstrate that problem-solving therapy is effective in reducing the burden on caregivers of children with cerebral palsy. DESIGN: Randomized clinical trial. LOCATION: Check primary care within a private nonprofit association. PARTICIPANTS: 140caregivers divided into control group (CG) and experimental group (EG). INTERVENTIONS: We performed in both groups a psychosocial intervention with a frequency of one session per week for three weeks to complete 120minutes. In the EG performed a shortened form of problem-solving therapy with a focus on caregiver burden and the CG performed an educational intervention focusing on respiratory diseases. MAIN MEASURES: The response variable corresponds to the score obtained by Zarit questionnaire. The independent variable accounted for psychosocial intervention. RESULTS: In the EG according to Zarit questionnaire score was obtained by averaging 45.0 points pre intervention against 45.3 points in the CP after intervention Zarit was obtained by averaging 29.8 points in the EG and 44.3 points in the CG (P<.0001). The catalog groups according to their score Zarit in charge: none, mild, moderate and severe impact differences were found in the different intervention categories (Wilcoxon test Z=6.281, P<.00001). CONCLUSIONS: Problem solving therapy is effective in reducing the burden on caregivers of children with cerebral palsy.

[Epidemiological and clinical characteristics of the COVID-19 epidemic in Mexico: Quintana Roo case]. / Características epidemiológicas y clínicas de la epidemia COVID-19 en México: caso Quintana Roo.

Objective: Identify risk factors for severe outcome in Mexican patients with COVID-19 in the population of Quintana Roo. Material and methods: Study of 5,916 who met the criteria for suspected cases of COVID-19, 2,531 confirmed by qrTPCR-Sars-CoV-2 tests, of which 1,486 were positive, among which they were classified as hospitalized (severe COVID-19) and outpatients. Multivariate logistic regression analysis was performed to explore the factors associated with the severity of COVID-19 and death as clinical outcomes. The basic reproduction number (R0) was calculated Statistical analysis) Endorsement of the ethics committee 2301. Results: SARS-CoV-2 positive patients presented a high prevalence of hypertension 29.1%, diabetes 23.5%, obesity 24%, and 48.5% have at least one chronic disease. There is a high risk of severity for COVID-19 in patients with diabetes OR=3.14, hypertension OR=1.88, obesity OR=1.68, kidney disease OR=3.2, older than 65 years OR=13.6 and men OR=1.7. These factors also increase the risk of death up to 7.7 times. The maximum R0 during the epidemic was 2.4. Conclusion: Liver and kidney disease, diabetes, hypertension, and obesity are significantly associated with severe COVID-19 and death.

Estos factores también incrementan el riesgo de defunción hasta 7.7 veces. El R0 máximo durante la epidemia fue de 2.4. Conclusión: la enfermedad hepática, renal, diabetes, hipertensión y obesidad se asocian significativamente a COVID-19 severo y defunción.

Symptom attribution and stress level in patients with medically unexplained symptoms in a Mexican emergency department.

Background: Patients who come to the emergency department are different from those seen in outpatient clinics. The former suffer greater stress. Aim: Establish an association between the attribution of the symptoms (psychosocial or organic) by the patient and the level of perceived stress in patients with Medically Unexplained Physical Symptoms (MUS) in an emergency department. Methods: A correlational cross-sectional study was conducted in 138 patients with MUS in the emergency department of a 3rd level public hospital where the psychosocial or organic attribution of nonspecific symptom(s) by patients and the perceived stress were measured with validated scales. Bivariate analysis was performed with Chi square for categorical variables, and a Spearman correlation, p <0.05. Results: 75% of patients with psychosocial attribution have higher stress compared to patients with organic symptom attribution (25%). In Spearman's correlation, a medium but statistically significant correlation was obtained. Conclusions: The psychosocial attribution of the patient's complaint might coexist in MUS patients with higher level of perceived stress by the patients. Health professionals might need to address both psychosocial attributions and stress in MUS patients.

Strategies for Increasing the Role of Family Medicine in Mexican Health Care Reform.

There is little or no role for primary care and family medicine in current health reforms in Mexico. However, robust evidence shows that primary care helps prevent morbidity and mortality and increases health equity. Mexico has participated in several international meetings sponsored by the World Organization of National Colleges, Academies and Academic Associations and the North American Primary Care Research Group that are aimed at increased understanding of national health systems and the need to strengthen primary care for improved health outcomes. From 1 of these meetings the Cancún Manifesto emerged, with a strategic plan to increase the stature and impact of the Mexican College of Family Physicians (COLMEXAC) in strengthening primary care in Mexico. We aim to describe this strategic plan and discuss its early implementation, and for this account to serve as a possible formula for other countries. The 5 specific strategies discussed are 1) the need for consensus on the leading role of the Mexican family physician in the national health system; 2) health ecology research; 3) to improve the perception of patients about the benefits of primary care and family medicine; 4) to organize meetings of health providers, users, and other stakeholders; and 5) to promote the professionalization of COLMEXAC as a legal entity.

Randomized clinical trial of the safety and immunogenicity of the Tdap vaccine in pregnant Mexican women.

Immunization with the tetanus, diphtheria, and pertussis (Tdap) vaccine raises controversies on immunogenicity and possible antibody interference. We performed an experimental, double-blind, parallel group controlled clinical trial to evaluate the safety and immunogenicity of the Tdap vaccine in 204 pregnant women and their children and to determine its interference in antibody production. Pregnant women 18 to 38 y of age with 12 to 24 weeks gestation, a low obstetric risk, and without serious disease were randomly selected. The experimental group received 0.5 mL IM of Tdap and the control group normal saline. Six blood samples were drawn before and after solution application, and from the umbilical cord of the infants and at 2, 4, and 6 months of age. Pertactin and Pertussis toxin antibodies and possible interference of maternal antibodies with the vaccine were determined. In the experimental group, antibodies against Bordetella pertussis pertactin (anti-PRN) (112 E/mL 95% CI 89.9-139.9) and antibodies against pertussis toxin (anti-PT) (24.0 E/mL, 95% CI 18.3-31.4) were elevated in the mother before vaccination. These were higher in the umbilical cord and descended in the infant at 2 months (71.4 (95% CI 56.8-89.7 and 10.9; 95% CI 8.7-13.7, respectively). Anti-PT showed a delay in production. Tdap safety was confirmed with only mild local pain at 24 and 48 hours. Anti-PRN and anti-PT antibodies in the infant descend at 2 months of age. There is a delay in anti-PT in children of immunized mothers. Further studies are needed to elucidate its clinical significance.

Health care utilization of mexican patients with medically unexplained physical symptoms.

OBJECTIVE: To determine the prevalence of medically unexplained physical symptoms and the characteristics and use of health services in a group of patients with medically unexplained physical symptoms and a group of patients with other illnesses. METHODS: This was a cross-sectional, retrospective and multicenter study. We included 1,043 patients over 18 years of age from 30 primary care units of a government health institution, in 11 states of Mexico, attended by 39 family physicians. The prevalence of medically unexplained physical symptoms was determined and both groups with or without symptoms were compared with regard to drug use, laboratory and other studies, leaves of absence, and referrals in the last six months. The group with medically unexplained physical symptoms was diagnosed using the Patient Health Questionnaire and the diagnostic criteria of Reid et al. Emergency or terminal illnesses were excluded. The chi square test was used with a statistical significance of p < 0.05. RESULTS: Medically unexplained physical symptoms was diagnosed in 73 patients (7.0%). The majority were women (91.8%); their predominant symptom was from the gastrointestinal system in 56 (76.7%). This group had a greater use of clinical studies and referrals to other services (mean 1.1 vs. 0.5; p <0.0001 and 0.6 vs. 0.8; p < 0.01, respectively). CONCLUSIONS: The prevalence of medically unexplained physical symptoms was low, but with a greater impact on some health services. This could represent an overload in medical costs. OBJETIVO: Determinar la prevalencia de Síntomas Físicos Medicamente No Explicables y las características y uso de los servicios de salud entre el grupo de pacientes con Síntomas Físicos Medicamente No Explicables, y el grupo con otras enfermedades. MÉTODOS: Estudio transversal, retroprospectivo y multicéntrico. Se incluyeron a 1,043 pacientes mayores de 18 años, en 30 unidades de atención primaria de una institución gubernamental en salud, en 11 estados de la República Mexicana, atendidos por 39 médicos familiares. Se estimó la prevalencia de Síntomas Físicos Medicamente No Explicables y se compararon los dos grupos con y sin estos síntomas, en cuanto al uso de medicamentos, estudios de laboratorio, de gabinete, incapacidades y referencias en los últimos seis meses. El grupo de Síntomas Físicos Medicamente No Explicables fue diagnosticado por el Patient Health Questionnaire (son los síntomas físicos más comúnmente referidos por estos pacientes en el primer nivel de atención), además de criterios diagnósticos de Reid et al. Se excluyeron urgencias o con enfermedad terminal. Se utilizó prueba Chi cuadrada con p <0.05 para significancia estadística. RESULTADOS: El 7.0% (73) se diagnosticó como Síntomas Físicos Medicamente No Explicables, la mayoría mujeres (91.8%); el síntoma predominante pertenece al sistema gastrointestinal con 76.7% (56). Este grupo demandó mayor uso de estudios de gabinete y referencias a otros servicios (media 1.1 vs. 0.5; p <0.0001 y 0.8 vs 0.6; p <0.01, respectivamente). CONCLUSIONES: La prevalencia de Síntomas Físicos Medicamente No Explicables fue baja, pero con impacto significativo en el uso de algunos servicios de salud. Esto pudiera representar un mayor costo comparado con otro grupo de pacientes.

Auto- medicación y auto-prescripción en el personal de salud del primer nivel de atención de México, Bolivia y Ecuador / Selfmedication and selfprescription in health care workers in primary care in Mexico, Bolivia and Ecuador

Introducción. La prevalencia general de la automedicación en la población general fluctúa de 27.3% a 61.3%. En trabajadores de la salud está menos documentado (Definido como auto prescripción), así como su frecuencia y las características del personal médico. Material y métodos. Se trata de un estudio comparativo transversal de 3 países, México (178), Bolivia (250) y Ecuador (130) en población de Médicos Familiares y Médicos Generales de Primer nivel de atención en salud; sexo y edad indistintos, activos en consulta pública o institucional. El muestreo fue por conveniencia calculado por fórmula. Se usó una encuesta con datos demográficos, Frecuencia de automedicación y auto prescripción, patologías donde se usaron, y razones de uso y fuentes de información. Se capturaron y analizaron en SPSS versión 20. Se utilizaron estadísticas descriptivas e inferenciales como ji-cuadrada y Kruskal Wallis. Aprobado por el comité de ética de dos países. Resultados. De los participantes 58.0% son médicos familiares, la mayoría femeninas (p<.05), con pareja, y con promedio de edad de 39.3. Laboran en el sistema público 42.2%. Se automedicaron y auto prescribieron más medicamentos los médicos en México y menos en Ecuador (p<.0001). En general, en el último mes, 61.5% de los profesionales estudiados se auto medicó (media 2.99 veces), y menor porcentaje se auto prescribió 35.8%, (media 1.28 veces) principalmente analgésicos y antibióticos (p<.0001) y por patologías respiratorias (p<.05). Las variables numéricas no cumplieron los supuestos de normalidad. Conclusión. Más de la mitad de los profesionales estudiados se auto medicó y más de un tercio se auto prescribió (antibióticos y analgésicos), esto más en México (AU)

Introduction. The general prevalence of selfmedication in the general population fluctuates from 27.3% to 61.3%. It is less documented in health workers (denominated as selfprescription), as well as its frequency and the characteristics of medical personnel. Material and methods. This is a cross- sectional, comparative study of 3 countries, Mexico (178), Bolivia (250) and, Ecuador (130) in the population of Family Physicians and General Practitioners of the first level of care; indistinct sex and age, active practice in public or institutional consultation. Sampling was for convenience calculated by a formula. A survey with demographic data, II Frequency of self-medication and self-prescription, pathologies where they were used, reasons for use and, sources of information were used. They were captured and analyzed in SPSS version 20. Descriptive and inferential statistics such as chi-square and Kruskal Wallis were used. It was approved by the ethic committee from two countries. Results. Of the participants, 58.0% are family doctors, the majority female (p <.05), with a partner, and with an average age of 39.3 years; 42.2% work in the public system. More physicians in Mexico and fewer in Ecuador used self-medicated and self- prescribed medications (p <.0001). In general in the last month, 61.5% of the professionals self-medicated (average 2.99 times), and a lower percentage (35.8%,)self-prescribed (average 1.28 times) mainly pain relievers and antibiotics (p <.0001) and for respiratory pathologies (p <.05). The numerical variables did not meet the assumptions of normality. Conclusion. More than half of the professionals studied practice self-medication and more than third antibiotics and analgesics as self-prescription this more in Mexico (AU)

[Infusional therapy: an alternative for shouder pain post-laparoscopy]. / Terapia infusional: una alternativa en dolor de hombro post laparoscopia

INTRODUCTION: Neuraxial anesthesia in upper abdominal laparoscopic surgery decreases perioperative morbidity and mortality. However, shoulder pain is common and difficult to control. Use of a major opioid (e.g., fentanyl) for the control of this event may depress respiratory function. This is why we believe that a safe and effective therapeutic control of this disease pain is a multimodal analgesic scheme which we have called infusional therapy. OBJECTIVE: To compare various schemes for controlling shoulder pain secondary to pneumoperitoneum. METHODS: Nonrandomized clinical trial with 56 patients ASA I-II divided into four groups undergoing laparoscopic cholecystectomy. Group I (n= 15) managed with ketorolac 1 mg kg, group II (n = 12) ketoprofen 100 mg, group III (n = 14) ketoprofen 50 mg + 50 mg tramadol, and group IV (n = 15) ketoprofen 100 mg + 100 mg tramadol. The following ariables were analyzed: presence and intensity of pain, analgesia rescue and operative time. RESULTS: Group I had more shoulder pain events compared to other groups (p= 0.002) in the same way the group IV required less rescue analgesia (p= 0.034). CONCLUSION: preemptive analgesia to infusional therapy with ketoprofen-tramadol at doses of 100 mg each is safe for laparoscopic surgery.

Antecedentes: en cirugía laparoscópica del hemiabdomen superior la anestesia neuroaxial disminuye la morbilidad y mortalidad perioperatorias; sin embargo, el dolor de hombro es una afección frecuente de difícil control. Puesto que los fármacos opioides mayores (fentanilo) para el control del dolor deprimen la función respiratoria, consideramos que la terapia infusional es un tratamiento seguro y eficaz. Objetivo: comparar diversos esquemas analgésicos para el control del dolor de hombro secundario al neumoperitoneo. Material y método: ensayo clínico no aleatorizado, efectuado en 56 pacientes ASA I-II en cuatro grupos con colecistectomía laparoscópica. El grupo I (n= 15) se trató con ketorolaco 1 mg/kg, el grupo II (n= 12) con ketoprofeno 100 mg, el grupo III (n= 14) con ketoprofeno 50 mg más tramadol 50 mg, y el grupo IV (n= 15) con ketoprofeno 100 mg más tramadol 100 mg. Las variables analizadas fueron: dolor y su intensidad, analgesia de rescate y tiempo quirúrgico. Resultados: en el grupo I hubo más episodios de dolor de hombro que en el resto de los grupos (p= 0.002); el grupo IV requirió menos analgesia de rescate (p= 0.034). Conclusión: la analgesia preventiva con terapia infusional con ketoprofeno-tramadol, a dosis de 100 mg, es segura para pacientes intervenidos mediante cirugía laparoscópica.

CONCLUSIONS: A useful, short and accessible questionnaire to be applied in Primary Care has been validated to measure shared decision-making from the physician's perspective

Impacto de una intervención psicosocial en la carga del cuidador de niños con parálisis cerebral / Impact of a psychosocial intervention in caregiver burden of children with cerebral palsy

OBJETIVO: Demostrar que la terapia de resolución de problemas es eficaz para disminuir la carga en los cuidadores de niños con parálisis cerebral. DISEÑO: Ensayo clínico aleatorizado. Emplazamiento: Consulta de atención primaria dentro de una asociación privada no lucrativa. Participantes: Ciento cuarenta cuidadores divididos en un grupo control (GC) y un grupo experimental (GE). Intervenciones: Se realizó en ambos grupos una intervención psicosocial con una frecuencia de una sesión por semana durante 3 semanas a completar 120 min. En el GE se realizó una forma acortada de terapia de resolución de problemas con enfoque en la carga del cuidador y en el GC se realizó una intervención educativa con enfoque en enfermedades respiratorias. Mediciones principales: La variable respuesta corresponde a la puntuación obtenida mediante el cuestionario Zarit. La variable independiente correspondió a la intervención psicosocial. RESULTADOS: En el GE, de acuerdo con la puntuación del cuestionario Zarit, se obtuvo un promedio preintervención de 45,0 puntos contra 45,3 puntos en el GC; tras la intervención se obtuvo un promedio Zarit de 29,8 puntos en el GE y de 44,3 puntos en el GC (p < 0,0001). Se catalogó a los grupos según su puntuación Zarit en carga: nula, leve, moderada y severa, encontrando diferencias del impacto de la intervención en los diversas categorías (prueba de Wilcoxon Z = -6,281, p < 0,00001). CONCLUSIONES: La terapia de resolución de problemas es efectiva para disminuir la carga en los cuidadores de niños con parálisis cerebral

OBJECTIVE: To demonstrate that problem-solving therapy is effective in reducing the burden on caregivers of children with cerebral palsy. DESIGN: Randomized clinical trial. Location: Check primary care within a private nonprofit association. Participants: 140 caregivers divided into control group (CG) and experimental group (EG).Interventions: We performed in both groups a psychosocial intervention with a frequency of one session per week for three weeks to complete 120 minutes. In the EG performed a shortened form of problem-solving therapy with a focus on caregiver burden and the CG performed an educational intervention focusing on respiratory diseases.
