Effectiveness of Saccharomyces Boulardii CNCM I-745 probiotic in acute inflammatory viral diarrhoea in adults: results from a single-centre randomized trial.

BACKGROUND: Probiotics are effective for treating acute infectious diarrhoea caused by bacteria, but there are inconsistent results for the effectiveness of probiotics for diarrhoea caused by viruses. In this article we want to determine whether Sb supplementation has an effect on acute inflammatory viral diarrhoea diagnosed with the multiplex panel PCR test. The aim of this study was to evaluate the efficacy of Saccharomyces boulardii (Sb) as a treatment in patients diagnosed with viral acute diarrhoea. METHODS: From February 2021 to December 2021, 46 patients with a confirmed diagnosis of viral acute diarrhoea diagnosed with the polymerase chain reaction multiplex assay were enrolled in a double-blind, randomized placebo-controlled trial. Patients received paracetamol 500 mg as a standard analgesic and 200 mg of Trimebutine as an antispasmodic treatment plus 600 mg of Sb (n = 23, 1 × 109/100 mL Colony forming unit) or a placebo (n = 23) orally once daily for eight days. The improvement in and severity of symptoms were measured using a symptom diary, the Patient Global Impression and the Patient Global Impression of Change scales (days 4 and 8), both answered and recorded by the patient. RESULTS: Of the 46 patients who completed treatment, 24 (52%) were men and 22 (48%) were women. The average age was 35.6 ± 12.28 years (range 18 to 61 years). The average duration of the evolution of illness at the time of diagnosis was 0.85 ± 0.73 days (maximum 2 days). On day 4 after the diagnosis, 20% reported pain and 2% reported fever, but on day 8, no patient reported pain or fever. On day 4, 70% of patients in the Sb group and 26% in the placebo group reported improvement (P = 0.03), based on the Patients' Global Impression of Change scale, which assesses patient's rating of overall improvement. These findings suggest that 3 to 4 days of treatment with Sb helped to improve symptoms of diarrhoea caused by a virus. CONCLUSION: Treatment with Sb on acute inflammatory diarrhoea of viral aetiology shows no changes regarding the severity of the symptoms; nevertheless, it seems to impact improvement positively.

Gender Differences in Postoperative Pain, Nausea and Vomiting After Elective Laparoscopic Cholecystectomy.

BACKGROUND: Although reports suggest that pain and postoperative nausea and vomiting (PONV) may be more frequent in women, the evidence is inconsistent. The objective of this study was to investigate whether women are more sensitive to pain and PONV after laparoscopic cholecystectomy (LC). METHODS: A total of 370 women and 275 men were included in a retrospective cohort study. All underwent LC under standardized general anesthesia. The variables analyzed included clinical and anthropometric parameters. End points were the incidence of nausea, vomiting, pain, and the requirement for additional pain relievers and antiemetics to control these. RESULTS: The women were younger and had lower body weight than the men (p < 0.001). Body mass index was within the normal range for 50% of women and 30% of men (p < 0.001). Pain was more common in women at 1, 6, 12 and 24 h after surgery (p < 0.02). Narcotics in addition to the doses used to lessen pain intensity (p = 0.01) were required in 60 women and 19 men (p < 0.001). PONV was more frequent in women at 1 and 6 h after surgery (p < 0.01). Rescue antiemetics were required in 35 women and 11 men (p = 0.008). Hospital stay was shorter for men (p < 0.001). Four patients in each group developed postoperative complications (p = 0.14). There was no mortality. CONCLUSIONS: Early postoperative pain, nausea and vomiting after LC were more common in women, who more frequently required analgesic and antiemetic rescue medication.

Bone regeneration in mandibular fractures after the application of autologous mesenchymal stem cells, a randomized clinical trial.

BACKGROUND/AIM: Facial injury in adults can commonly result in fractures of the mandible. Autologous mesenchymal stem cells (AMSCs) transplantation is proposed as an alternative to conventional graft treatment to improve bone regeneration. The aim was to evaluate the effectiveness of AMSCs application in mandibular fractures to reduce regeneration time and increase bone quality. MATERIALS AND METHODS: This study was a single-blind controlled clinical trial conducted in patients with mandibular angle fractures. Patients were divided into two groups: study group fracture reduction plus application of AMSCs and control group only fracture reduction. AMSCs were obtained from adipose tissue 24 h before the procedure. Intensity and density were evaluated in normal bone and fractured bone at 4 and 12 weeks after surgery using panoramic radiography and computed tomography. RESULTS: A total of 20 patients, 10 in each group, were included. The study group had a mean age of 31.2 ± 6.3 years, and the control group mean age was 29.7 ± 7.2 years. All patients were male. Bone quality measured in grey levels at week 4 was 108.82 ± 3.4 vs 93.92 ± 2.6 (P = 0.000) using panoramic radiography and 123 ± 4.53 vs 99.72 ± 5.72 (P = 0.000) using computed tomography. At week 12, the measurements were 153.53 ± 1.83 vs 101.81 ± 4.83 (P = 0.000) using panoramic radiography and 165.4 ± 4.2 vs 112.9 ± 2.0 (P = 0.000) using tomography in the study and control groups, respectively. CONCLUSION: Similar ossification values were obtained after 4 weeks when the use of AMSCs was compared to simple fracture reduction. However, after 12 weeks, the AMSCs group had a 36.48% higher ossification rate.

[Approach to percutaneous nephrolithotomy. Comparison of the procedure in a one-shot versus the sequential with metal dilata]. / Abordaje para nefrolitotomía percutánea. Comparación del procedimiento en un solo paso contra la secuencial con dilatadores metálicos.

INTRODUCTION: Percutaneous nephrolithotomy is an efficient approach for treatment of different types of kidney stones. Various types of access techniques have been described like sequential dilatation and one-shot procedure. OBJECTIVE: To determine the differences in time of exposure to X-rays and hemoglobin levels between techniques. METHODS: Controlled clinical trial. Patients older than 18 years with complex/uncomplicated kidney stones, without urine infection were included. They were assigned randomly to one of the two techniques. Response variables were determined before and 24 h after procedures. RESULTS: 59 patients were included: 30 underwent one-shot procedure (study-group) and 29 sequential dilatation (control-group). Baseline characteristics were similar. Study group had a lower postoperative hemoglobin decline than control group (0.81 vs. 2.03 g/dl, respectively; p < 0.001); X-ray exposure time (69.6 vs. 100.62 s; p < 0.001) and postoperative creatinine serum levels (0.93 ± 0.29 vs. 1.13 ± 0.4 mg/dl; p = 0.039). No significant differences in postoperative morbidity were found. CONCLUSION: One-shot technique demonstrated better results compared to sequential dilatation.

Efficacy of metronidazole versus placebo in pain control after hemorrhoidectomy. Results of a controlled clinical trial.

INTRODUCTION: Hemorrhoidal disease occurs in 50% of people aged > 40 years and is the most common reason for anorectal surgery. Pain is the main complication. Multiple topical and systemic drugs have been investigated for pain control, but there is no ideal treatment. Metronidazole has been shown to decrease postoperative pain but is not used widely. OBJECTIVE: To evaluate the effect of oral metronidazole versus placebo and to assess postoperative pain following hemorrhoidectomy. MATERIAL AND METHODS: Controlled clinical trial in adult patients who underwent elective hemorrhoidectomy for grade III/IV hemorrhoids. Patients were assigned to receive metronidazole (500 mg q8 h orally; study group, SG) or placebo (control group, CG) for 7 days after surgery. Pain was assessed using a visual analog scale after surgery. Analgesic administration (time and use of analgesics) and resumption of daily life activities were also assessed. RESULTS: Forty-four patients were included, 22 in each group. Postoperative pain differed significantly between the SG and CG at 6 h (3.86 ± 0.56, 6.64 ± 1.49), 12 h (5.59 ± 1.33, 8.82 ± 0.79), 24 h (6.86 ± 1.49, 9.73 ± 0.45), day 4 (5.32 ± 2.10, 9.50 ± 0.59), day 7 (3.14 ± 1.03, 7.36 ± 1.39), and day 14 (2.14 ± 0.46, 5.45 ± 1.29). The first analgesia dose was required at 21.27 ± 5.47 h in the CG and 7.09 ± 2.36 h in the SG (p < 0.05), the time of analgesic use was 6.86 ± 1.61 days in the CG and 13.09 ± 2.48 days in the SG (p < 0.05), and resumption of daily activities occurred at 7.59 ± 1.56 days in the CG and 14.73 ± 3.76 days in the SG (p < 0.05). CONCLUSION: Oral administration of metronidazole is effective in pain management after hemorrhoidectomy.

Introducción: la desnutrición intrahospitalaria se ha descrito hace más de 70 años como un problema frecuente. En México se reportan cifras de entre el 20% al 50%; sin embargo no se ha estudiado su prevalencia ni su asociación con la morbilidad y mortalidad hospitalaria.Objetivos: evaluar el estado nutricional y su relación con la morbimortalidad hospitalaria en pacientes mexicanos.Métodos: cohorte prospectiva de pacientes que ingresaron en un hospital de referencia para una estancia hospitalaria mayor de 5 días. Se capturó peso, talla, índice de masa corporal (IMC), estado nutricional de acuerdo con la valoración global subjetiva (VGS) a su ingreso y egreso hospitalario, así como diagnóstico médico, complicaciones y mortalidad. Los datos fueron analizados mediante la prueba T de Student, prueba Chi-cuadrado y prueba Exacta de Fisher.Resultados: se incluyeron 610 pacientes en total, con un promedio de edad de 50,8 ± 17,32 años, 267 mujeres (43,8%) y 343 hombres (56,2%). Del total, 154 fueron catalogados con sospecha de desnutrición o desnutrición (pacientes expuestos, 25,2%) y 456 bien nutridos (pacientes no expuestos, 74,8%), con una relación de 1 a 3. La morbilidad total de la cohorte tuvo un RR = 2,70, IC 95 % (2,06-3,55) y la mortalidad con un RR = 2,64, IC 95% (1,74-4,0), siendo ambas estadísticamente significativas (p = 0,001).Conclusiones: el diagnóstico de desnutrición al ingreso hospitalario constituye un factor de riesgo para el desarrollo de complicaciones y mortalidad. Este padecimiento al ingreso en comparación con el paciente que no presenta desnutrición incrementó el riesgo de mortalidad hasta en 2.64 veces.

Introduction: Malnutrition after hospital admission has been described over 70 years as a very common health problem. In Mexico, data reported go from 20-50%, but the prevalence and its association with short-term morbidity and mortality has not been studied. Objectives: To evaluate the nutritional status and its association with hospital morbidity and mortality in adult Mexican patients. Methods: Prospective cohort study of 610 adult patients admitted in the Specialties Hospital, Western National Medical Center, with a hospital stay longer than 5 days and in whom weight and height could be measured. Nutritional diagnosis of patients at admission and discharge of the hospital, diagnosis of disease, complications and death were recorded. Nutritional status was obtained using the Subjective Global Assessment (SGA). Data was analyzed using Student ́s t Test, Chi-square Test and Fisher´s Exact Test. Results: A total of 610 patients were included with a mean age of 50.8 ± 17.32 years; 267 (43.8%) were female and 343 (56.2%) male. A total of 154 patients (25.2%) were in risk of malnutrition or malnourished and 456 (74.8%) well-nourished according to SGA, (p = 0.001). Difference in weight and BMI were statistically signifi cant between both groups (p = 0.001). The total cohort morbidity had a RR = 2.70, with 95% CI (2.06-3.55), and mortality RR = 2.64, with a 95% CI (1.74-4.0), both with a significant difference (p = 0.001). Conclusions: Malnutrition at hospital admission constitutes a risk factor for complications or mortality in patients admitted for more than 5 days. This condition at admission compared to a well-nourished patient increased risk of mortality by up to 2.64 times (AU)
