RESUMEN
OBJECTIVE: To evaluate the quality of sexual life in men with spinal cord injury. DESIGN: Cross-sectional analytical study. PATIENTS: Males with a history of spinal cord injury who attended an outpatient rehabilitation service. METHODS: An analytical study examined adult male patients with complete spinal cord injury in rehabilitation. A modified Sexual Life Quality Questionnaire (SLQQ) examined quality of sexual life, with scores below 50 suggesting significant sexual dysfunction and dissatisfaction. The assessment evaluated age, occupation, marital status, comorbidities, and treatment methods. RESULTS: A total of 80 patients were included; 33 (41%) had a thoracic spinal cord injury, and 47 (59%) had a lumbar spinal cord injury. Thirty-seven patients (46%) were dissatisfied with the quality of their sexual life; 29 patients (88%) with thoracic spinal cord injury and 8 patients (17%) with lumbar spinal cord injury were dissatisfied with the quality of their sexual life (p = 0.001). Patients with higher education level experienced less sexual dissatisfaction (p = 0.03). CONCLUSION: Human sexuality involves numerous interconnected elements that impact on general health. Sexual pleasure, self-esteem, and personal relationships are crucial for patients with spinal cord injury to identify rehabilitation needs. These results indicate the importance of supporting sexual well-being in recovery. Further studies of sexual enjoyment and quality of life for patients with spinal cord injury are needed, using larger and more diverse populations.

The emergence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants of concern (VOCs) presents global heterogeneity, and their relative effect on pediatric severity is still limited. In this study, we associate VOCs with pediatric clinical severity outcomes in Mexico. Bioinformatics methods were used to characterize VOCs and single amino acid (aa) mutations in 75,348 SARS-CoV-2 genetic sequences from February 2020 to October 2022. High-predominance VOCs groups were calculated and subsequently associated with 372,989 COVID-19 clinical pediatric outcomes. We identified 21 high-frequency mutations related to Omicron lineages with an increased prevalence in pediatric sequences compared to adults. Alpha and the other lineages had a significant increase in case fatality rate (CFR), intensive critical unit (ICU) admission, and automated mechanical ventilation (AMV). Furthermore, a logistic model with age-adjusted variables estimated an increased risk of hospitalization, ICU/AMV, and death in Gamma and Alpha, in contrast to the other lineages. We found that, regardless of the VOCs lineage, infant patients presented the worst severity prognoses. Our findings improve the understanding of the impact of VOCs on pediatric patients across time, regions, and clinical outcomes. Enhanced understanding of the pediatric severity for VOCs would enable the development and improvement of public health strategies worldwide.
RESUMEN
Background: Breastfeeding is a characteristic process of mammals that ensures delivery of an adequate nutritional supply to infants. It is the gold standard food source during an infant's first months of life. Since the onset of the COVID-19 pandemic in 2020, people in quarantine have experienced a wide range of feelings, which may make isolation challenging in terms of maternal health. This study focused on the prevalence of breastfeeding practices and postpartum depression (PPD) among Mexican women during the COVID-19 pandemic. Materials and Methods: This cross-sectional study included 586 postpartum women who completed an online survey 4-8 weeks after delivery from April to December 2020 in Guadalajara, Mexico. The aim was to identify potentially depressed mothers according to the Edinburgh Postnatal Depression Scale (EPDS) and describe their breastfeeding practices. Results: The mean maternal age was 30.4 ± 4.6 years, the mean EPDS score was 9.6 ± 5.0, and the PPD prevalence according EPDS scores was 27.1%. Exclusive breastfeeding (EBF) was reported by 32.3% of mothers in the first 48 h and by 70.3% of mothers 48 h after delivery. EBF was associated with a lower prevalence of PPD during the first 48 h (p = 0.015) and after the first 48 h (p = 0.001) after delivery. Skin-to-skin contact (SSC) was reported by 385 (65.7%) mothers. PPD was less frequent in mothers practicing SSC (20.3%) than it was in those not practicing SSC (40.3%) (p = 0.001). A higher percentage of mothers practiced SSC breastfed (66.9%) and used EBF (150, 79.4%) (p = 0.012 and 0.001, respectively). Conclusions: Results suggest that the pandemic emergency and restrictions imposed on the population significantly affected the well-being of mothers after birth, and that these effects may have posed risks to the mental health and emotional stability of postpartum mothers. Therefore, encouraging BF or EBF and SSC may improve or limit depressive symptoms in postpartum mothers.

Background: Surgical site infection (SSI) is a major complication of surgical procedures and contributes to morbidity, mortality, and healthcare costs. It is commonly caused by Gram-negative bacteria and should be monitored in hospital units. Objective: To identify critical points to implement an antibiotic form for surgical wound infection management. Material and methods: Descriptive observational study in 100 cultures of wounds with SSI. The most common diagnosis, the microorganism involved, sensitivity to antibiotics and prescription consistency were identified. In addition, demographic variables were assessed and a questionnaire was applied to surgeons in order to identify the critical points to implement a local formulary of antibiotics. Results: 37% of cultures came from female patients. The most common diagnosis was hollow viscus perforation in 31%. The most common microorganism was Escherichia coli ESBL in 20% and 55% of these were sensitive to imipenem. The critical points observed were consistency in the prescription of antimicrobials, which reached only 29%, and that surgeons did not actively participate in strategies for the rational use of antibiotics. Conclusions: As a critical point to implement the antibiotic form, little involvement of surgeons with the hospital infection control team was found. The incidence of SSI was 2.4%, predominantly in emergency surgery. The presence of E. coli ESBL is frequent, with resistance to broad-spectrum antimicrobials.
Introducción: las infecciones del sitio quirúrgico (ISQ) son una complicación importante de los procedimientos quirúrgicos y contribuyen a la morbilidad, la mortalidad y los costos sanitarios. Comúnmente son causadas por bacterias Gram-negativas y deben ser monitoreadas en las unidades hospitalarias. Objetivo: identificar puntos críticos para implementar un formulario de antibióticos para el manejo de infección de herida quirúrgica. Material y métodos: estudio observacional descriptivo en 100 cultivos de heridas con ISQ. Se identificó el diagnóstico más común, el microorganismo involucrado, la sensibilidad a los antibióticos y la congruencia de la prescripción. Además, se evaluaron variables demográficas y se aplicó un cuestionario a cirujanos para identificar los puntos críticos para implementar un formulario local de antibióticos. Resultados: el 37% de los cultivos procedieron de pacientes mujeres. El diagnóstico más común fue perforación de víscera hueca en el 31%. El microrganismo más común fue Escherichia coli BLEE en el 20% y el 55% de estos fueron sensibles a imipenem. Los puntos críticos observados fueron la congruencia en la prescripción de antimicrobianos que alcanzó solo 29% y que los cirujanos no participaron activamente en las estrategias del uso razonado de antibióticos. Conclusiones: como punto crítico para implementar el formulario de antibióticos se encontró poca participación de los cirujanos con el equipo hospitalario de control de infecciones. La incidencia de ISQ fue del 2.4% y preedominaron en la cirugía de urgencia. La presencia de E. coli BLEE es frecuente, con resistencia en antimicrobianos de amplio espectro.

Resumen OBJETIVO: Identificar los factores asociados con la recidiva de cáncer de mama en pacientes con cirugía conservadora. MATERIALES Y MÉTODOS: Estudio observacional, de cohorte retrospectiva, efectuado a partir de expedientes de pacientes con cáncer de mama en estadios tempranos e intervenidas con cirugía conservadora. Parámetros de estudio: estadio, subtipo histológico, perfil de expresión de receptores hormonales, tiempo de seguimiento, recidiva y periodo libre de enfermedad. La tasa de recidiva, el periodo libre de enfermedad y la identificación de los factores asociados con recidiva se hicieron con análisis estadístico. RESULTADOS: Se estudiaron 53 pacientes con edad media de 51.0 ± 9.4 años. El subtipo histopatológico más frecuente fue el ductal en 49 de las 53 pacientes; en 48 de ellas los tumores fueron positivos para receptores de progesterona, en 7 de 53 para Her-2 y en 3 de 53 triple negativo. La tasa de recidiva de cáncer de mama fue de 13.2% (es decir: 7 de 53 pacientes). El tiempo libre de enfermedad en quienes recayeron fue de 30.6 ± 24.8 meses. En el análisis bivariado se asociaron significativamente con recidiva: los ganglios linfáticos positivos, la expresión de receptores de progesterona y de estrógenos, los tumores triple negativo y el tratamiento complementario con quimioterapia. En el análisis multivariado solo se asociaron con recidiva: tener un tumor triple negativo (OR = 51.8; IC95%: 4.9- 548.4; p = 0.001) y recibir quimioterapia (OR = 8.0; IC95%: 1.4-46.1; p = 0.020). CONCLUSION: Los factores asociados con la recidiva fueron los ganglios linfáticos positivos, la expresión de receptores de progesterona y de estrógenos, tumores triple negativo y recibir quimioterapia.
Abstract OBJECTIVE: To identify factors associated with breast cancer recurrence in patients undergoing conservative surgery. MATERIALS AND METHODS: Observational, retrospective cohort study conducted on the records of patients with early-stage breast cancer who underwent conservative surgery. Study parameters: stage, histologic subtype, hormone receptor expression profile, follow-up time, recurrence and disease-free period. Statistical analysis was performed to estimate recurrence rate and disease-free period and to identify factors associated with recurrence. RESULTS: Fifty-three patients with a mean age of 51.0 ± 9.4 years were evaluated. The most common histopathologic subtype was ductal in 49 of 53 patients; tumors were progesterone receptor positive in 48, Her-2 positive in 7 of 53, and triple negative in 3 of 53. The breast cancer recurrence rate was 13.2% (i.e., 7 of 53 patients). Disease-free time in those who relapsed was 30.6 ± 24.8 months. In bivariate analysis, positive lymph nodes, progesterone and estrogen receptor expression, triple-negative tumors, and adjuvant chemotherapy were significantly associated with recurrence. In multivariate analysis, only having a triple-negative tumor (OR = 51.8; 95%CI: 4.9-548.4; p = 0.001) and receiving chemotherapy (OR = 8.0; 95%CI: 1.4-58.4; p = 0.001) were associated with recurrence. CONCLUSION: Factors associated with recurrence were positive lymph nodes, expression of progesterone and estrogen receptors, triple-negative tumors, and receipt of chemotherapy.

Abstract Objective: To measure the waiting time in granting a final diagnosis to the rights holders with BI RADS 4 and 5 from 40 to 69 years old, in the General Hospital of the Zone + Family Medicine No.1 in La Paz, Baja California Sur, Mexico. Material and methods: Observational, descriptive study, with the review of 36 mammography control records from the radiology area, with BI RADS 4 or 5 results. Demographic variables and waiting times for the process were measured from mammography request until the final diagnosis. Descriptive statistics were performed. Study considered without risk according to the General Health Law. It was authorized by the ethics and research committees of the hospital unit. Results: A total of 36 screening files were analyzed in women between 40 and 69 years old, with a mean of 51.86 + 8.28 years. The average number of days elapsed from the request for the mammography to the final diagnosis was 125.05 + 66.23. In 13.9% of the cases, the diagnostic process was concluded in the normal scheduled time; for the remaining 86.1%, it took more than 30 days to complete the diagnostic protocol. The causes of the prolonged time were attributable to the delay in care at the second level (consultation of specialties and pathology area). Conclusions: It is necessary to generate strategies in all the steps of the process, to ensure that the waiting time regulated in the flowchart is complied with, both in the first and second level of care; to improve the prognosis of patients with breast cancer.
RESUMEN
Melasma is a common circumscribed hypermelanosis of sun-exposed areas of the skin. Platelet-Rich Plasma therapy has been evidenced to inhibit melanin synthesis in animals and humans. To determine the effectiveness of platelet-rich plasma as a treatment for melasma. Twenty female patient with melasma were involved in this study. The intervention included three Platelet-Rich Plasma application sessions at 15-day intervals. Patients were evaluated before and after treatment. Variables measured included the facial melanin concentration using the melasma area and severity index score, melasma quality of life scale satisfaction grade, and histologic changes. Mean age was 41 ± 7 years. An initial MELASQOL score of 42 ± 14.8 and final score of 16.6 ± 7.2 (p = 0.008) were reported; the initial and final MASI score were 15.5 ± 8.4 and 9.5 ± 7.2 (p = 0.001), respectively. The dermatoscopy examination revealed a decrease in pigmentation after intervention (p = 0.001). Histopathologic improvement was detected in reductions in cutaneous atrophy (14 [70%] vs. 11 [55%]), solar elastosis (15 [75%] vs.11 [55%]), and inflammatory infiltrate (9 [45%] vs. 6 [30%]), before and after treatment, respectively. The intervention was associated with decreased intensity of the melasma patch and improved skin quality, shown by the MELASQOL and MASI scores.

RESUMEN
INTRODUCTION: Many experimental studies have examined multiple drugs or treatments to improve the healing of intestinal anastomoses. Synthetic prostacyclin analogs, immunosuppressants, erythropoietin, growth hormone, insulin-like growth factor type 1, synthetic metalloproteinases inhibitors, and hyperbaric oxygen therapy have produced promising results in low-risk models of anastomosis dehiscence. However, in high-risk models, only hyperbaric oxygen therapy has been shown to be useful. Pirfenidone (PFD), a commonly used antifibrosing drug, has not been shown to be effective for this purpose. Our objective was to evaluate the effects of PFD on anastomosis healing and adhesion genesis in a low-risk rat model of dehiscence of colonic anastomosis. METHODS: An experimental study was conducted on 40 healthy Wistar rats randomly assigned to the control group or PFD experimental group (20 rats in each group). Colon anastomosis was performed 3 cm above the peritoneal reflection using the same technique in all animals. Mechanical resistance was studied by measuring bursting pressure. Adhesions were evaluated macroscopic and histologically using common staining techniques. Animals received the first PFD dose 12 h after surgery at a dose of 500 mg/kg one a day (SID) for 5 consecutive days. On day 6, the animals were reoperated on to measure the bursting pressure in situ and to classify adhesions macroscopically, and the anastomosed colon was resected for histological analysis. RESULTS: There were no deaths, complications, or anastomosis dehiscence in either group. The mean bursting pressure was 120.8 ± 11 mm Hg and 135.5 ± 12.4 in the control and PFD groups, respectively (p < 0.001). The adhesions were less dense and had less inflammatory cell infiltration in the PFD group (p < 0.02 and 0.002, respectively). Collagen content was slightly higher in the PFD group (p = 0.04). CONCLUSIONS: Our results revealed favorable effects of PFD in this low-risk colon anastomosis model; for example, the bursting pressure was higher, and the macroscopic adhesions were soft and exhibited less inflammatory infiltration and higher collagen content in the PFD group than in the control group. The results showing that PFD treatment was associated with better healing of minor adhesions seem to be paradoxical because the therapeutic indications for this drug are directed at treating fibrosing diseases.

INTRODUCTION: Intra-abdominal adhesions' main etiology is surgical procedures that commonly require reintervention. Oral treatments with sildenafil, zafirlukast, and pirfenidone have yielded decreased severity of fibrotic phenomena secondary to the introduction of foreign material. This study aimed to evaluate the efficacy of oral zafirlukast, sildenafil, or pirfenidone treatment on reducing or preventing intra-abdominal adhesions in an experimental rat model. METHODS: Four groups, each of 10 male Wistar rats weighing 250-300 g, were used. A midline laparotomy was used to excise an area of 1.5 × 1.5 cm and reconstructed with polypropylene mesh fixed to the abdominal wall. After 12 h, oral doses of zafirlukast (1.25 mg/kg, group B), sildenafil (15 mg/kg, group C), or pirfenidone (500 mg/kg, group D) were given every day for 8 days. The control group, A, received no treatment. At day 9, animals were reoperated. The implant was resected after ethically approved euthanasia, and specimens were fixed in 10% formaldehyde for histopathology. RESULTS: Control group A yielded adhesions with greater fibrovascular density and neighboring organ involvement than the other groups (p = 0.001), as well as intense inflammatory infiltrates and numerous granulomas (p = 0.04). Adhesions in group C had less fibrovascular density (p = 0.03) with decreased serosal injuries (p = 0.001) and less organ involvement. Group D had reduced adhesions without organ involvement (p < 0.01) and less inflammatory infiltrates, collagen fibers, and foreign body granulomas than group B or C (p < 0.01). CONCLUSIONS: Oral administration of these agents did not prevent adhesions but ameliorated them. Oral pirfenidone offered the best performance and could be recommended for human use.

OBJECTIVES: This observational cross-sectional study examined changes in substance use during the coronavirus disease 2019 (COVID-19) pandemic in the Mexican population and evaluated whether depression or anxiety was associated with these new consumption patterns. METHODS: An online survey was distributed to the general population. Participants were questioned about their demographics, situation during the COVID-19 pandemic, and substance consumption patterns. The Patient Health Questionnaire-9 for depression and the Coronavirus Anxiety Scale were used. RESULTS: A total of 866 individuals completed the survey. The mean scores for the Patient Health Questionnaire-9 and Coronavirus Anxiety Scale were 8.89 ± 6.20 and 3.48 ± 3.22, respectively. The preferred substances were alcohol (19%), tobacco (16.5%), and marijuana (5.6%). Consumption of alcohol (p = 0.042) significantly increased during the pandemic and it was higher in women than in men (p = 0.040). CONCLUSIONS: Substance use patterns were affected by the pandemic, with an increase in the number of users and consumption rate, as well as the reported psychiatric symptoms.

BACKGROUND: Postoperative symptoms and pain after laparoscopic cholecystectomy (LC) are common in women. However, there is no evidence of differences in incidence and severity among different age groups. We evaluated whether adverse postoperative symptoms were more common in younger than in older women after LC. METHODS: One hundred and fifty premenopausal (mean age 37.6 ± 3.6 y) and 145 postmenopausal women (59 ± 5.2 y) were included in this retrospective cohort study. Clinical and anthropometric parameters were analyzed. Study endpoints were the incidences of postoperative nausea and vomiting (PONV) and pain, and the additional analgesics and antiemetics needed after surgery. RESULTS: Body mass index was normal in 42.7% of patients in the younger group and 64.8% in the older group (P < 0.001). Reported pain was more frequent and intense in the younger group throughout the study period (P < 0.01). Additional narcotics were required in 18% of premenopausal versus 7.6% of postmenopausal women (P = 0.001), and the doses used to reduce pain were higher for premenopausal women (P = 0.02). PONV was more frequent in the younger group at 1 and 6 h after surgery (P < 0.005). Rescue antiemetics were required in 29 premenopausal and 13 postmenopausal women (P = 0.01). Hospital stay was shorter for the older patients (P = 0.01). Minor morbidity was observed in both groups (0.7% and 2.1%). There was no mortality. CONCLUSIONS: Early PONV and pain after LC were more frequent in premenopausal women, who also required more rescue analgesic and antiemetic medication.

Introduction: Vaccines against COVID-19 are effective. However, a percentage of people with a complete vaccination scheme are at risk of contracting and becoming ill from COVID-19. These cases are known as "vaccinated cases of infection". Objective: To identify the clinical characteristics of patients with SARS-CoV-2 infection with a history of vaccination for COVID-19. Methods: Retrospective cohort study in 271 vaccinated and positive patients who attended medical units in Baja California Sur, with or without a complete scheme and registered in SINOLAVE. Clinical characteristics, management, sequelae and mortality were analyzed. Descriptive statistics and association measures were used. Authorized by the ethics and research committees. Results: Age 48.5 ± 12.1 years, 19.5% met the definition of infection in vaccinated, 93% with outpatient management, 3.7% mortality, the most frequent comorbidity: diabetes / hypertension. 92% of the cases vaccinated with Cansino had COVID, followed by Pfizer with 26%. There is a higher risk of hospitalization and mortality in patients with an incomplete scheme. Conclusions: The vaccines are effective, most of the cases were ambulatory. Patients vaccinated with Cansino showed a higher COVID infection, the reinforcement of this vaccine could reduce the disease in patients already vaccinated. Of the patients who died, the majority did not have a complete vaccination schedule.
Introducción: Las vacunas contra la COVID-19 son efectivas. Sin embargo, un porcentaje de personas con esquema completo de vacunación tiene riesgo de contagiarse y enfermar por COVID-19. Estos casos se conocen como "casos de infección en vacunados". Objetivo: Identificar las características clínicas de los pacientes con infección por SARS-COV-2 con antecedente de vacunación para COVID-19.Métodos: Estudio de cohorte retrospectivo con 271 vacunados y positivos que acudieron a las unidades médicas en Baja California Sur, con esquema completo o sin él y registrados en el SINOLAVE. Se analizaron características clínicas, manejo, secuelas y mortalidad. Se utilizó estadística descriptiva y medidas de asociación. El estudio fue autorizado por los comités de ética e investigación. Resultados: Edad: 48.5 ± 12.1 años; 19.5% cumplieron con la definición de infección en vacunados; 93% con manejo ambulatorio; mortalidad del 3.7%; la comorbilidad mas frecuente: diabetes/hipertensión. El 92% de los casos vacunados con Cansino presentaron COVID, seguido por los que recibieron Pfizer, con el 26%. Existe mayor riesgo de hospitalización y mortalidad en pacientes con esquema incompleto. Conclusiones: las vacunas son efectivas, la mayoría de los casos fueron ambulatorios. Los pacientes vacunados con Cansino mostraron mayor infección por SARS-CoV-2; el refuerzo de esta vacuna, podría disminuir la enfermedad en los pacientes ya vacunados. De los pacientes que murieron, la mayoría no tenía esquema completo de vacunación.

Coronaviruses can cause respiratory, gastrointestinal, and central nervous system diseases in humans and animals, have the ability to adapt through mutations, and are programmed to modify host tropism. SARS-CoV-2 infection (COVID-19) has been shown to be a highly thrombogenic disease, generating deep vein thrombosis, pulmonary embolism and acute ischemia, in patients even without previous pathology. Coronaviruses can cross the species barrier and infect humans with unexpected consequences for public health. The transmission rate of SARS-CoV-2 is higher compared to that of closely related SARS-CoV infections. Key residues of the spike protein have a higher binding affinity for ACE2. These may be the reason for the higher transmission rate of SARS-CoV-2. COVID-19 has been shown in some patients to be a highly thrombogenic disease, both venous and arterial, generating deep vein thrombosis, pulmonary embolism and acute ischemia, both in patients without previous pathology as with them.There is molecular evidence of the state of hyper coagulability in COVID-19; the first observations were made by Wang, in 2020, when analyzing the levels of fibrinogen and D-dimer in patients with COVID-19 and finding elevated levels up to 75% above the laboratory controls. We present the case of a 62-year-old male with mild symptoms of COVID-19 and outpatient management, at the end of the clinical disease he presented an acute abdomen secondary to mesenteric ischemia, with good postoperative evolution.
Los coronavirus pueden causar enfermedades respiratorias, gastrointestinales y del sistema nervioso central en seres humanos y animales; tienen la capacidad para adaptarse por medio de mutaciones y son programados para modificar el tropismo del huésped. La infección por el SARS-CoV-2 (COVID-19) genera trombosis venosa profunda, embolismo pulmonar y cuadros de isquemia aguda, en pacientes sin afección previa. Los coronavirus infectan a los seres humanos con consecuencias inesperadas para la salud pública. La tasa de transmisión de la infección por el SARS-CoV-2 es más alta en comparación con las infecciones por SARS-CoV estrechamente relacionadas. Los residuos clave de la proteína espiga tienen mayor afinidad de unión por el receptor de la enzima convertidora de angiotensina (ECA2). Esta puede ser la razón de la mayor tasa de transmisión de SARS-CoV-2. La COVID-19 ha demostrado, en algunos pacientes, ser una enfermedad altamente trombogénica, tanto venosa como arterial, dado que genera trombosis venosa profunda, embolismo pulmonar y cuadros de isquemia aguda, tanto en pacientes sin afecciones previas como con ellas. Existe evidencia molecular del estado de hipercoagulabilidad en la COVID-19; las primeras observaciones fueron realizadas por Wang en 2020, al analizar los niveles de fibrinógeno y dímero-D en pacientes con COVID-19, y encontrar niveles elevados hasta 75% por arriba de los controles de laboratorio. Se presenta el caso de un paciente masculino de 62 años, con un cuadro leve de COVID-19 y abordaje ambulatorio; al término de la enfermedad clínica presentó abdomen agudo secundario a isquemia mesentérica, con buena evolución en el posoperatorio.

Background: Health professionals recommend increasing your water intake, to 8 cups per day to reduce weight. Despite the widespread adoption of this advice, the evidence for its efficacy is limited. Objective: To evaluate the substitution of sweetened beverages for plain water as an intervention to decrease the body mass index (BMI) in health workers. Materials and methods: An analytical, quasi-experimental, longitudinal and prospective study was carried out at the HGZ MF #1 from October 15, 2019 to April 15, 2020. A collection instrument was developed to collect information to evaluate water intake in IMSS workers, recommending the consumption of simple water at 8 cups per day and determined anthropometric measurements at the beginning and at the end of the study. Results: Data collection was carried out on 150 healt workers who agreed to participate. The age was 40.1 ± 8.4 years, with a greater distribution in women with 60.0%, the majority belonged to the morning shift (46.0%). After the intervention, we found that only 9.3% had an intake of less than 1 l/day, 23.3% from 1 to 1.5 l/day, and 67.3% had the recommended intake of 1.6 to 2 l/day. The initial weight was 87.0 ± 17.4 kilograms vs. 84.1 ± 15.4 kilograms at the end. For its part, the initial BMI was 31.1±4.8 kg/m2 and the final BMI was 30.1 ± 4.4 kg/m2 . Inferential analysis using the test of differences for paired samples identified a statistically significant difference in favor of the intervention for BMI with a mean reduction of 1.004 kg/m2 (95% CI 0.776-1.232, p < 0.001). Conclusions: The substitution of sweetened beverages for plain water as an intervention to decrease the BMI in IMSS workers with statistically significant results that adopt our working hypothesis.
Antecedentes: Los profesionales de la salud recomiendan aumentar el consumo de agua a 8 tazas por día para reducir el peso. A pesar de la adopción de este consejo, la evidencia de su eficacia es limitada. Objetivo: Evaluar la sustitución de bebidas edulcoradas por agua simple como intervención para disminución del índice de masa corporal (IMC) en trabajadores sanitarios. Materiales y métodos: Se llevó a cabo un estudio analítico, cuasiexperimental, longitudinal y prospectivo, en el Hospital General de Zona / Medicina Familiar N° 1, de La Paz, México, del 15 de octubre de 2019 al 15 de abril de 2020. Se desarrolló un instrumento de recolección para recopilar información para evaluar la ingesta de agua en trabajadores de la salud, recomendando el consumo de agua simple de 8 tazas por día; se determinaron medidas antropométricas al inicio y al final del estudio. Resultados: Se realizó la recolección de los datos de 150 trabajadores del Instituto Mexicano del Seguro Social (IMSS) que aceptaron participar. La edad fue de 40.1 ± 8.4 años, con una distribución mayor en mujeres, con 60.0%; la mayoría pertenecía al turno matutino (46.0%). Luego de la intervención, encontramos que solo el 9.3% tenía ingesta de menos de 1 l/día, el 23.3% de 1 a 1.5 l/día y el 67.3% presentó la ingesta recomendada de 1.6 a 2 l/día. El peso inicial fue de 87.0 ± 17.4 kg vs. 84.1 ± 15.4 kg al final. Por su parte, el IMC inicial fue 31.1 ± 4.8 kg/m2 y final de 30.1 ± 4.4 kg/m2 . El análisis inferencial mediante la prueba de diferencias para muestras emparejadas identificó una diferencia estadísticamente significativa en favor de la intervención para el IMC, con una reducción media de 1.004 kg/m2 (IC 95%: 0.776 a 1.232, p < 0.001). Conclusiones: La sustitución de bebidas edulcoradas por agua simple como intervención para disminución del IMC en trabajadores del IMSS, logró resultados estadísticamente significativos, que confirman nuestra hipótesis de trabajo.

BACKGROUND: Evidence suggests that a preoperative single-dose steroid improves lung function and decreases the incidence of postoperative symptoms; however, this has not been sufficiently proved in modified radical mastectomy for cancer. This study aimed to evaluate the efficacy of preoperative single-dose steroid administration for postoperative lung function and postoperative symptoms in women undergoing modified radical mastectomy for breast cancer. METHODS: In this controlled clinical trial, conducted between June 2014 and October 2018, we examined 81 patients. Patients received a preoperative single dose of 8 mg dexamethasone (n=41; treatment group) or placebo (sterile injectable water; n=40; control group). We obtained data on postoperative nausea and vomiting and pain intensity and performed spirometry 1 h before and 1, 6, 12, and 24 h after surgery. The use of additional analgesic or antiemetic drugs was recorded. We followed up patients 30 days after discharge and recorded any surgical or medical complications. RESULTS: The age distribution and anthropometric variables of the two groups were similar. Almost 50% of the patients in each group also underwent breast reconstruction. In the treatment group, pain intensity was always lower, the incidence of postoperative nausea and vomiting was lower at 6, 12, and 24 h, and additional analgesics or antiemetics were required less frequently (P<0.05 for all). Both treatment and control groups demonstrated a restrictive ventilatory pattern immediately after surgery, which in the treatment group was reversed after 24 h. However, the reconstructed patients had a more intense and prolonged restrictive pattern (P<0.05). Surgical morbidity included one seroma observed in the control group. No infections occurred at the surgical site or at any other level, and no patient developed any metabolic disorder. No mortality was observed in either group. CONCLUSIONS: This study establishes that a single preoperative dose of dexamethasone markedly decreased the incidence of postoperative nausea and vomiting and pain, improved respiratory parameters, and decreased the need for additional postoperative analgesic or antiemetic drugs. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov (ID NCT02305173).
RESUMEN
INTRODUCTION: Introduction: many obese children will be obese adults unless they adopt and maintain healthy eating and physical activity patterns. Anxiety has been described in overweight and obese children with dysfunctional family environments, with impact on their quality of life; risk for some eating disorder was also found. Objective: to identify anxiety in the presence of food in schoolchildren in Baja California Sur. Material and methods: a cross-sectional study in 406 schoolchildren, from 8 to 13 years of age, was performed: nutritional status calculation, measurements of attitudes towards food (cut-off point > 20), socioeconomic level, type of family, and intake of junk food were collected. Descriptive statistics and association measures were performed using Student's t-test and the chi-squared test. Parents provided their informed consent, and children provided their assent. Results: a total of 406 schoolchildren were evaluated, with ages of 10.4 ± 1.2. Of these, 53 % had healthy weight, 44 % had overweight or obesity, and 3 % were underweight. Functional families predominated at 67 %. A middle socioeconomic level was found in 64 %. In all, 94 % consumed junk food. There is an association between anxiety in the presence of food and socioeconomic status, and anxiety in the presence of food and nutritional status (p = 0.01). In overweight and obese schoolchildren no association was found between study variables. There is anxiety in the presence of food in 40 % of the sample due to external factors, in 5 % because of tiredness or boredom, in 11 % because of negative feelings. Conclusion: there is an association between anxiety, socioeconomic status, and nutritional status. Anxiety in the presence of food occurred in 54.7 % of cases.
INTRODUCCIÓN: Introducción: muchos niños obesos serán adultos obesos a menos que adopten y mantengan patrones saludables de alimentación y actividad física. Se han descrito: ansiedad en niños con sobrepeso y obesidad en ambientes de familias disfuncionales, repercusión en la calidad de vida y riesgo de algún desorden alimenticio. Objetivo: identificar la ansiedad en presencia de alimentos en escolares de Baja California Sur. Material y métodos: estudio de tipo encuesta trasversal en 406 escolares de 8 a 13 años de edad; se realizó un cálculo del estado nutricional y se efectuó una medición del test de actitudes hacia la alimentación (punto de corte de > 20); se recopilaron el nivel socioeconómico, el tipo de familia y la ingesta de comida chatarra. Se realizó una estadística descriptiva con medidas de asociación mediante la prueba t de Student y prueba de chi2. Se obtuvieron el consentimiento informado de los padres y el asentimiento del menor. Resultados: se evaluaron 406 escolares con edades de 10,4 ± 1,2. El 53 % presentaron peso saludable, el 44 % sobrepeso y obesidad, y el 3 % bajo peso. Predominó la familia funcional con un 67 %. Se consttó un nivel socioeconómico medio en el 64 %. El 94 % consumen alimentos chatarra. Existe asociación entre ansiedad en presencia de alimentos y nivel socioeconómico, y entre ansiedad en presencia de alimentos y estado nutricional (p = 0,01). En los escolares con sobrepeso y obesidad no se encontró asociación entre las variables del estudio. Existe ansiedad en presencia de alimentos en el 40 % por factores externos, en el 5 % por cansancio o aburrimiento y en el 11 % por sentimientos negativos. Conclusión: existe asociación entre ansiedad, nivel socioeconómico y estado nutricional. La ansiedad en presencia de alimentos se presentó en el 54,7 % de los casos.
