Functional features of the exopolysaccharide extracts produced by Lactiplantibacillus strains isolated from table olives.

This study evaluates the functional characteristics of the exopolysaccharide (EPS) extracts produced by various strains of Lactiplantibacillus pentosus (LPG1, 119, 13B4, and Lp13) and Lactiplantibacillus plantarum (Lp15) isolated from table olives. None of the EPS crude extracts showed cytotoxicity when administered to THP-1 human macrophage cells at dosages ranging from 6.25 to 50 µg mL-1. Many exhibited anti-inflammatory properties (reduction of pro-inflammatory cytokines TNF-α and IL-6 production) and antioxidant activity (reduction of ROS%) when macrophages were stimulated with Escherichia coli lipopolysaccharide. Notably, the EPS extract produced by the L. pentosus LPG1 strain had the best results corroborated by western blot immune analysis for differential expression of COX-2, Nrf-2, and HO-1 proteins, with the most significant antioxidant and anti-inflammatory response observed at a dosage of 50 µg mL-1. Chemical analysis revealed that the EPS extract produced by this strain contains a heteropolymer composed of mannose (35.45%), glucose (32.99%), arabinose (17.93%), xylose (7.48%), galactose (4.03%), rhamnose (1.34%), and fucose (0.77%). Finally, we conducted response surface methodology to model the EPS extract production by L. pentosus LPG1 considering pH (3.48-8.52), temperature (16.59-33.41 °C) and salt concentration (0.03-8.77% NaCl) as independent variables. The model identified linear effects of salt and pH and quadratic effects of salt as significant terms. The maximum EPS extract production (566 mg L-1) in a synthetic culture medium (MRS) was achieved at pH 7.5, salt 7.0%, and a temperature of 20 °C. These findings suggest the potential for novel applications for the EPS produced by L. pentosus LPG1 as nutraceutical candidates for use in human diets.

Effects of Music on the Quality of Life of Family Caregivers of Terminal Cancer Patients: A Randomised Controlled Trial.

The aim of this study was to investigate the effects of listening to self-chosen music on the quality of life of family caregivers of cancer patients receiving palliative home care. A total of 82 family caregivers were assigned either to the intervention group (n = 41) or to the control group (n = 41) in this double-blind, multicentre, randomised controlled clinical trial. The recruitment period was between July 2020 and September 2021. The intervention group received individualised pre-recorded music in daily 30 min sessions for 7 consecutive days. The control group was given a recorded repetition of the basic therapeutic training education also in 30 min sessions for 7 consecutive days. The primary endpoint assessed was the caregivers' quality of life (Quality of Life Family Version and European Quality of Life visual analogue scale) before and after the intervention. The secondary endpoint was their perceived satisfaction with the intervention (Client Satisfaction Questionnaire). The music intervention was successful, producing a tangible improvement in the caregivers' quality of life (p < 0.01) and satisfaction with the care provided (p = 0.002). The intervention was not only effective but produced no adverse effects. This study encourages the use of self-chosen music as a complementary intervention in nursing care for family caregivers of palliative cancer patients.

Effect of Self-Chosen Music in Alleviating the Burden on Family Caregivers of Patients with Advanced Cancer: A Randomised Controlled Trial.

The experience of caregiver burden among family members of patients with advanced cancer is a common problem. The aim of this study was to determine whether the burden may be alleviated by means of a therapeutic approach based on self-chosen music. This randomised controlled trial (ClinicalTrials.gov, NCT04052074. Registered 9 August 2019) included 82 family caregivers of patients receiving home palliative care for advanced cancer. The intervention group (n = 41) listened to pre-recorded, self-chosen music for 30 min/day for seven consecutive days, while the control group (n = 41) listened to a recording of basic therapeutic education at the same frequency. The degree of burden was assessed by the Caregiver Strain Index (CSI), calculated before and after the seven-day intervention. According to this measure, caregiver burden fell significantly in the intervention group (CSI change: -0.56, SD 2.16) but increased in the control group (CSI change: +0.68, SD 1.47), with a significant group x moment interaction F(1, 80) = 9.30, p = 0.003, η2p = 0.11. These results suggest that, in the short term at least, the use of therapy based on self-chosen music alleviates the burden on family caregivers of palliative cancer patients. Moreover, this therapy is easy to administer at home and does not present any problems in practice.

Hyperbaric oxygenation therapy improve recovery in early or late vascular occlusion generates by tissue fillers.

INTRODUCTION: Aesthetic medicine is characterized by the efficacy and safety of treatments. Although sometimes adverse events could be occurred, in this case vascular occlusion is the most serious of them. The tissue is deprived of oxygen and there is a possibility of necrosis, so it is necessary to remove the tissue filler and promote oxygenation. OBJECTIVE: We propose the hyperbaric oxygenation treatment to oxygenate the tissue after vascular occlusion generated by a tissue filler such as Hyaluronic Acid. RESULTS: We show how hyperbaric oxygenation treatment is an adjuvant therapy after vascular occlusion, improving tissue regeneration and prevent or limit scars or sequelae. CONCLUSION: Hyperbaric oxygenation treatment is a safe and effective method to treat vascular accident, improving tissue oxygenation in early cases and improving tissue regeneration in cases with necrosis.

Effects of a concurrent training, respiratory muscle exercise, and self-management recommendations on recovery from post-COVID-19 conditions: the RECOVE trial.

The aim of this study was to determine the effectiveness of physical exercise, respiratory muscle training, and the self-management World Health Organization (WHO) recommendations leaflet on the recovery of physical fitness, quality of life, and symptom status in people with post-COVID-19 conditions. Eighty nonhospitalized adults with a post-COVID-19 condition were randomly assigned to one of four 8-wk parallel intervention groups: 1) multicomponent exercise program based on concurrent training (CT, number of subjects (n) = 20; 3 resistance and endurance supervised sessions per week at low-moderate intensity); 2) inspiratory muscle training (RM, n = 17; 2 standardized daily sessions); 3) a combination of both of the above (CTRM, n = 23); and 4) control group (CON, n = 20; following the WHO guidelines for post-COVID-19-related illness rehabilitation). No significant differences between groups were detected at baseline. Although no significant differences between interventions were detected in the V̇o2max, significant individual improvements were identified in the CT (7.5%; effect size, ES = 0.28) and CTRM (7.8%; ES = 0.36) groups. Lower body muscle strength significantly improved in the CT and CTRM (14.5%-32.6%; ES = 0.27-1.13) groups compared with RM and CON (-0.3% to 11.3%; ES = 0.10-0.19). The CT and CTRM groups improved significantly for dyspnea and fatigue, as did the health status. In addition, significant differences between interventions were described in fatigue and depression scales favoring CT and CTRM interventions. An individualized and supervised concurrent training with or without inspiratory muscle training was safe and more effective than self-care recommendations and inspiratory muscle training alone, to regain cardiovascular and muscular fitness, improve symptom severity, and health status in outpatients with post-COVID-19 conditions.NEW & NOTEWORTHY Eight weeks of concurrent training, with or without inspiratory muscle exercise, was better than WHO "Support for Rehabilitation: Self-Management after COVID-19-Related Illness" recommendations or inspiratory muscle training alone to improve cardiopulmonary fitness, strength, and symptom severity, in a safe and effective manner. The RECOVE trial proved the benefits and utility of a supervised exercise program in people with post-COVID-19 conditions after mild COVID-19 in an ambulatory setting.

Safety and Effectiveness of a Single Multiallergen Subcutaneous Immunotherapy in Polyallergic Patients.

BACKGROUND: As the number of allergic sensitizations increases the severity of allergic respiratory diseases worsens. Multiple monoallergen immunotherapy can be accompanied by poor treatment adherence and high costs, single multiallergen immunotherapy needs to prove efficacy whilst maintaining a good safety profile. METHODS: Observational, retrospective, multicenter study using a 2-pollen single undiluted multiallergen subcutaneous immunotherapy (SCIT) in routine clinical practice in Spain. Patients with rhinoconjunctivitis, with/without controlled asthma, sensitized to grass, olive, Parietaria, Cupressus, plane tree and/or Salsola pollen were included. Primary and secondary clinical efficacy endpoints were quality of life (mini Rhinitis Quality of Life Questionnaire (miniRQLQ)) and visual analogue scale (VAS) respectively. All adverse events were documented. RESULTS: Ten centers included 97 patients, median age 32 years. SCIT treatment included combinations of grass mix with olive, Parietaria, Cupressus, plane tree or Salsola or olive with Parietaria, Cupressus or Salsola. The mean duration of SCIT was 1.8 years with a high treatment adherence (73%). Significant improvement in quality of life, nasal and ocular symptoms, activity limitations and practical problems (p< 0.0001) and other symptoms (p= 0.024) was observed. Most patients did not develop asthma-like symptoms and a significant improvement of all allergic symptom severity was perceived. VAS showed a significant improvement in rhinoconjunctivitis and asthma by patients and physicians. Twenty-nine patients experienced adverse reactions, 25 had local and 6 had systemic reactions. CONCLUSIONS: Single undiluted multiallergen SCIT treatment of two different pollens is efficacious and safe in both children and adults, showing that it is a suitable option for the treatment of polyallergic patients.

Uses, abundance perception, and potential geographical distribution of Smilax aristolochiifolia Mill (SMILACACEAE) on the Totonacapan Region of Puebla, Mexico.

BACKGROUND: In some regions of Mexico, edible wild plants have been displaced or eliminated from the traditional food systems, mainly by changes in land use, booming monoculture, herbicide use, and by changes among the new generations in the traditional foods and diets of indigenous populations. In the Totonacapan region of Puebla, the gradual change from the traditional acahual plantation to coffee-type agroecosystems has provoked the displacement of old-growth forests and the eradication of wild plants since 1970. One of the wild species which has been used in traditional medicine and food recipes by the Totonac culture is Smilax aristolochiifolia (SMILACACEAE), known as "kgentsililh". This species forms part of traditional Totonac recipes, in which the tender stems are still used in local medicine to treat menstrual pain, deal with dysentery, and prevent hair loss. According to the Maxent® Program, there are still potential areas with habitats suitable to promote its conservation in the Poblano Totonacapan. METHODS: We conducted 260 interviews with people in 13 locations in the northern Sierra of the State of Puebla. Variables taken into account in the interview related to the consumption frequency of the species, its abundance and distribution perception, reasons or arguments given by the Totonac indigenous population about the decreased presence of specimens of S. aristolochiifolia, its dates of collection, and the cutting prices of kgentsililh at the community level and in local markets. The relative abundance of S. aristolochiifolia was determined through 22 samples in 2ts of 600 m2. Later, its potential distribution in the state of Puebla was estimated using the Maxent® Program Ver. 3.3.3. RESULTS: Of the 260 Totonac families interviewed, 31% had stopped consuming kgentsililh. The residents reported that in the last 50 years the populations of this plant had diminished in the northern Sierra of the State of Puebla, mainly due to changes in land use, herbicide application, over-collection, and urban growth. In traditional medicine, the stem sap of S. aristolochiifolia is currently employed to help treat baldness, and the "tuberous root" or plant rhizome is used to prepare a tea infusion to treat dysentery. The cost of plant guides varies from 10.00 to 40.00 Mexican pesos for one bunch (around 0.5 to 2.00 US dollars), and every bundle consists of between 7 to 10 cuttings from 0.4 to 0.5 m long. From our 22 quadrats of sampling and collection of S. aristolochiifolia, we were able to recognize a total of 32 specimens. There is a considerable abundance of kgentsililh in acahual plantations and old-growth forests (evergreen lowland and mid-elevation perennial forest) concerning the coffee-type plantations and milpas. According to our analysis using the Maxent Program®, eight physical and climatic variables have a direct relationship to the potential distribution of the species. CONCLUSIONS: Smilax aristolochiifolia is still a plant of socioeconomic importance, mainly because of its food value and its use in traditional medicine by indigenous families in Poblano Totonacapan. It is evident that the villagers perceive that in the last 50 years the species has decreased its population mainly due to land-use change, the application of herbicides to the different family production units, and climate change. At the moment, there is no knowledge about the methods of propagation of the species, and therefore there is no intention on the part of the population to conserve the species. However, it would be of great importance to generate a biocultural conservation strategy and take advantage of the results obtained from the potential geographic distribution area, since according to the Maxent® Program, there are still potential areas with habitat suitable to promote conservation in Poblano Totonacapan.

[Active surveillance for testicular tumors: adherence and safety.] / Adherencia y seguridad de la vigilancia activa en tumores de testículo.

INTRODUCTION: The active surveillance (AS) of testicular tumors (seminoma and non-seminoma) is the most frequent management option in the stage I disease. Relapses generally occurred within the first 3 years and <5% appear after this time cut-off point is fulfilled. Therefore, the adherence is one of the most important pillars in the AS protocol. The aim of this study is to evaluate the adherence to the AS protocol in a community hospital and, in turn, evaluate the safety of it emphasizing in the relapse-free rate in patients with and without risk factors. MATERIALS AND METHODS: A retrospective study of all the patients included in the AS protocol with seminoma tumors (ST) or non-seminoma tumors (NST) stage I was performed. Postoperative controls were performed according to the NCCN (National Comprehensive Cancer Network) recommendations. Different variables were taken into account, emphasizing in the risk factors: testicular tumor >4cm and the rete testis invasion in the ST, the linfovascular invasion and the percentage>40% of embrionary carcinoma in the NST. Adherence to the AS protocol was evaluated, focusing on those patients who lost it and what time it occurred. RESULTS: A total of 64 patients were included. The median follow-up was 36 months (IC 21-48 months). 12 patients lost the follow-up during the protocol with a median follow-up of 27.5 months (IC 16-30 months). A 21.8% of patients entered in the AS protocol with some associated risk factor. Adherence follow-up was successful in the first year (96.8%) and decreased over time (92.2% at 24 months and 86.3% at 36 months). CONCLUSION: We presented an important adherence to the AS protocol in patients with clinical stage I testicular cancer and in our series there no recurrences after 36 months of follow-up.

INTRODUCCIÓN: La vigilancia activa (VA) de tumores testiculares seminoma (TS) y no-seminomas (TNS) es en la actualidad, la opción de manejo más frecuente utilizada en tumores testiculares estadio clínico I. Las recaídas dentro de este seguimiento se presentan generalmente dentro de los 3 años y <5% se presentan después de este periodo. La adherencia en la VA termina siendo un pilar fundamental.OBJETIVO: El objetivo de este trabajo es evaluar la adherencia al protocolo de vigilancia activa, y a su vez evaluar la seguridad de esta opción de manejo haciendo hincapié en la tasa libre de recaída en pacientes con y sin factores de riesgo.MATERIALES Y MÉTODOS: Se realizó un estudio retrospectivo de todos los pacientes incluidos en un protocolo de VA (TS y TNS estadio I). Se tomaron en cuenta diferentes variables, realizando hincapié en la evaluación de los diferentes factores de riesgo, tomando como tal en TS al tamaño testicular > de 4 cm y a la invasión de la rete testis en el resultado anatomopatológico. En cuanto a los TNS, la ILV y un porcentaje >40% de CE fueron los factores de riesgo evaluados. Se evaluó la adherencia al seguimiento del protocolo de VA, haciendofoco en aquellos pacientes que se perdieron del mismo y en qué momento ocurrió.RESULTADOS: Un total de 64 pacientes fueron incluidos a protocolo de VA. La mediana de seguimiento fue de 36 meses (IC 21-48 meses). De todos los pacientes incluidos en este estudio, 12 de ellos perdieron el seguimiento durante el esquema propuesto, presentando una mediana de seguimiento de 27,5 meses (IC 16-30 meses). Un 21,8% de pacientes ingresó al protocolo de VA con algún factor de riesgo asociado. La adherencia al seguimiento fue exitosa en el primer año con un porcentaje de adhesión que alcanzó el 96,8% y fue descendiendo con el paso del tiempo (92,2% a los 24 meses y 86,3% a los 36 meses).CONCLUSIÓN: En nuestra serie, se evidenció una marcada adhesión al protocolo de VA en pacientes con diagnóstico de tumor testicular estadio clínico I, sin registrar recurrencias después de los 36 meses de seguimiento.

Consumption of caffeinated beverages and kidney function decline in an elderly Mediterranean population with metabolic syndrome.

It remains unclear whether caffeinated beverages could have deleterious renal effects in elderly population with underlying comorbid conditions. We investigated the associations between coffee, tea, or caffeine intake and 1-year changes in glomerular filtration rate (eGFR) in a large Spanish cohort of overweight/obese elderly with metabolic syndrome (MetS). This prospective analysis includes 5851 overweight/obese adults (55-75 years) with MetS from the PREDIMED-Plus study. We assessed coffee, tea, and caffeine consumption from a validated food-frequency questionnaire and creatinine-based eGFR using the Chronic Kidney Disease Epidemiology Collaboration equation. Multivariate-adjusted regression models were applied to test associations between baseline coffee, tea, or caffeine intake and 1-year eGFR changes. Caffeinated coffee (> 2 cups/day) and tea (at least 1 cup/day) drinkers had 0.88 and 0.93 mL/min/1.73 m2 greater eGFR decrease respectively, compared to those with less than 1 cup/day of coffee consumption or non-tea drinkers. Furthermore, caffeinated coffee consumption of > 2 cups/day was associated with 1.19-fold increased risk of rapid eGFR decline > 3 mL/min/1.73 m2 (95% CI 1.01-1.41). Similarly, individuals in the highest (median, 51.2 mg/day) tertile of caffeine intake had a 0.87 mL/min/1.73 m2 greater eGFR decrease. Decaffeinated coffee was not associated with eGFR changes. In conclusion, higher consumption of caffeinated coffee, tea, and caffeine was associated with a greater 1-year eGFR decline in overweight/obese adults with MetS.

Effect of vitamin D supplementation on asthma control in patients with vitamin D deficiency: the ACVID randomised clinical trial.

BACKGROUND: The relationship between asthma and vitamin D deficiency has been known for some time. However, interventional studies conducted in this regard have shown conflicting results. OBJECTIVE: To evaluate the efficacy of vitamin D supplementation in asthmatic patients in improving the degree of control of asthma. METHODS: Randomised, triple-blind, placebo-controlled, parallel-group study in adult asthmatic patients with serum 25-hydroxyvitamin-D3 <30 ng/mL. The intervention group received oral supplementation with 16 000 IU of calcifediol per week, and the control group had placebo added to their usual asthma treatment. The study period was 6 months. The primary endpoint was the degree of asthma control as determined by the asthma control test (ACT). Secondary endpoints included quality of life measured using the mini Asthma Quality of Life Questionnaire, the number of asthma attacks, oral corticosteroid cycles, the dose of inhaled corticosteroids, number of emergency visits, unscheduled consultations with the primary care physician and hospitalisations for asthma. RESULTS: One hundred and twelve patients were randomised (mean age 55 years, with 87 (78%) being women). Of the 112 patients, 106 (95%) completed the trial. Half the patients (56) were assigned to the intervention group and the other half to the control group. A statistically significant clinical improvement was observed in the intervention group (+3.09) compared with the control group (-0.57) (difference 3.66 (95% CI 0.89 to 5.43); p<0.001) as measured using ACT scores. Among the secondary endpoints, a significant improvement in the quality of life was found in the intervention group (5.34), compared with the control group (4.64) (difference 0.7 (95% CI 0.15 to 1.25); p=0.01). CONCLUSION: Among adults with asthma and vitamin D deficiency, supplementation with weekly oral calcifediol compared with placebo improved asthma control over 6 months. Further research is needed to assess long-term efficacy and safety. TRIAL REGISTRATION NUMBER: NCT02805907.

Recommendations Based on Evidence by the Andalusian Group for Nutrition Reflection and Investigation (GARIN) for the Pre- and Postoperative Management of Patients Undergoing Obesity Surgery.

In order to develop evidence-based recommendations and expert consensus for nutrition management of patients undergoing bariatric surgery and postoperative follow-up, we conducted a systematic literature search using PRISMA methodology plus critical appraisal following the SIGN and AGREE-II procedures. The results were discussed among all members of the GARIN group, and all members answered a Likert scale questionnaire to assess the degree of support for every recommendation. Patients undergoing bariatric surgery should be screened preoperatively for some micronutrient deficiencies and treated accordingly. A VLCD (Very Low-Calorie Diet) should be used for 4-8 weeks prior to surgery. Postoperatively, a liquid diet should be maintained for a month, followed by a semi-solid diet also for one month. Protein requirements (1-1.5 g/kg) should be estimated using adjusted weight. Systematic use of specific multivitamin supplements is encouraged. Calcium citrate and vitamin D supplements should be used at higher doses than are currently recommended. The use of proton-pump inhibitors should be individualised, and vitamin B12 and iron should be supplemented in case of deficit. All patients, especially pregnant women, teenagers, and elderly patients require a multidisciplinary approach and specialised follow-up. These recommendations and suggestions regarding nutrition management when undergoing bariatric surgery and postoperative follow-up have direct clinical applicability.

External trigeminal nerve stimulation for drug resistant epilepsy: A randomized controlled trial.

BACKGROUND: External trigeminal nerve stimulation (ETNS) is an emergent, non-invasive neurostimulation therapy delivered bilaterally with adhesive skin electrodes. In previous studies, ETNS was associated to a decrease in seizure frequency in patients with focal drug-resistant epilepsy (DRE). OBJECTIVE: To determine the long-term efficacy and tolerability of ETNS in patients with focal DRE. Moreover, to explore whether its efficacy depends on the epileptogenic zone (frontal or temporal), and its impact on mood, cognitive function, quality of life, and trigeminal nerve excitability. METHODS: Forty consecutive patients with frontal or temporal DRE, unsuitable for surgery, were randomized to ETNS or usual medical treatment. Participants were evaluated at 3, 6 and 12 months for efficacy, side effects, mood scales, neuropsychological tests and trigeminal nerve excitability. RESULTS: Subjects had a median of 15 seizures per month and had tried a median of 12.5 antiepileptic drugs. At 12 months, percentage of responders was 50% in ETNS group and 0% in control group. Seizure frequency in ETNS group decreased by -43.5% from baseline. Temporal epilepsy subgroup responded better than frontal epilepsy subgroup (55.56% vs. 45.45%, respectively). Median stimulation intensity was 6.2 mA. ETNS improved quality of life, but not anxiety or depression. Long-term ETNS affected neither neuropsychological function, nor trigeminal nerve excitability. No relevant adverse events were observed. CONCLUSIONS: ETNS is an effective and well-tolerated therapy for focal DRE. Patients with temporal epilepsy showed a better response than those with frontal epilepsy. Future studies with larger populations may define its role compared to other neurostimulation techniques. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that ETNS reduces seizure frequency in patients with focal DRE.

Complementary music therapy for cancer patients in at-home palliative care and their caregivers: protocol for a multicentre randomised controlled trial.

BACKGROUND: Patients with advanced cancer, receiving at-home palliative care, are subject to numerous symptoms that are changeable and often require attention, a stressful situation that also impacts on the family caregiver. It has been suggested that music therapy may benefit both the patient and the caregiver. We propose a study to analyse the efficacy and cost utility of a music intervention programme, applied as complementary therapy, for cancer patients in palliative care and for their at-home caregivers, compared to usual treatment. METHOD: A randomised, double-blind, multicentre clinical trial will be performed in cancer patients in at-home palliative care and their family caregivers. The study population will include two samples of 40 patients and two samples of 41 caregivers. Participants will be randomly assigned either to the intervention group or to the control group. The intervention group will receive a seven-day programme including music sessions, while the control group will receive seven sessions of (spoken word) therapeutic education. In this study, the primary outcome measure is the assessment of patients' symptoms, according to the Edmonton Symptom Assessment System, and of the overload experienced by family caregivers, measured by the Caregiver Strain Index. The secondary outcomes considered will be the participants' health-related quality of life, their satisfaction with the intervention, and an economic valuation. DISCUSSION: This study is expected to enhance our understanding of the efficacy and cost-utility of music therapy for cancer patients in palliative care and for their family caregivers. The results of this project are expected to be applicable and transferrable to usual clinical practice for patients in home palliative care and for their caregivers. The approach described can be incorporated as an additional therapeutic resource within comprehensive palliative care. To our knowledge, no previous high quality studies, based on a double-blind clinical trial, have been undertaken to evaluate the cost-effectiveness of music therapy. The cost-effectiveness of the project will provide information to support decision making, thereby improving the management of health resources and their use within the health system. TRIAL REGISTRATION: The COMTHECARE study is registered at Clinical Trials.gov, NCT04052074. Registered 9 August, 2019.

[Recommendations of the GARIN group for dietary managing of patient with chronic kidney disease]. / Recomendaciones del grupo GARIN para el tratamiento dietético de los pacientes con enfermedad renal crónica.

INTRODUCTION: Background and objectives: by means of this update, the GARIN working group aims to define its position regarding the dietary treatment of patients with chronic kidney disease (CKD). In this area there are many aspects of uncertainty. Material and methods: bibliographical review and specific questions in advance were discussed and answered at a meeting in the form of conclusions. Results: the therapeutic action must be individualized and taking into account the degree of renal failure that the patient presents and their comorbidities. Regarding nutritional medical therapy, our group proposes three different levels of action, in which the recommendations of protein intake, fiber, fatty acids or potassium are different. In addition, we suggest using the phosphorus/protein ratio concept in adjusting the diet of the patient with CKD. We give recommendations regarding treatment in diabetes and artificial supplementation. Conclusions: these recommendations about dietary issues in patients with CKD can add value to clinical work.

INTRODUCCIÓN: Introducción y objetivos: en el tratamiento dietético de los pacientes con enfermedad renal crónica (ERC) existen muchas áreas de incertidumbre. El grupo de trabajo GARIN tiene como objetivo definir su posición en este campo. Material y métodos: revisión bibliográfica previa y reunión presencial en la que se discutieron y contestaron preguntas específicas sobre el tema. Resultados: la actuación terapéutica debe ser individualizada y atendiendo al grado de enfermedad renal que presente el paciente y a sus comorbilidades. En cuanto a la terapia médica nutricional, nuestro grupo propone tres niveles diferentes de actuación, en los que las recomendaciones de ingesta proteica, fibra, ácidos grasos o potasio son distintas. Además, sugerimos utilizar el concepto ratio fósforo/proteína en el ajuste de la dieta del paciente con ERC. Damos recomendaciones en cuanto al tratamiento en diabetes y en suplementación artificial. Conclusiones: estas recomendaciones aportan respuestas concretas sobre cuestiones comunes en la asistencia a pacientes con ERC.

Physicochemical characterization of goat milk produced in the Comarca Lagunera, Mexico.

The purpose of this study was to determine goat milk physicochemical parameters during the feed scarcity season. An evaluation was made for 398 milk samples from 80 multiparous goats belonging to three different production systems: (S1) mechanized milking grazing pasture and harvested residue (alfalfa) and grain supplemented; (S2) system grazing native pasture; and (S3) system grazing native pasture and grain supplemented. The general averages were: fat (FT) 4.0 ± 0.20%, protein (PR) 3.3 ± 0.05%, lactose (LC) 4.9 ± 0.09%, nonfat solids (NFS) 8.9 ± 0.13%, total solids (TS) 14.5 ± 0.20%, temperature (TM) 24.6 ± 1.06°C, and acidity (pH) 6.7 ± 0.049. Most of the physicochemical components of milk were affected (p < 0.0001) by the production system × month interaction and production system × group × month interaction. The FT content was higher (p < 0.05) in S2 (4.56 ± 0.18) than in S1 (3.64 ± 0.20) and S3 (3.50 ± 0.20). LC differed (p < 0.05) in S2 (5.07 ± 0.08) than in S1 (4.77 ± 0.09) and S3 (4.70 ± 0.09). No differences were observed for the rest of the variables (p < 0.05) among the production systems. The study unveiled a higher content of FT, LC, NFS, PR, and TS for S2 than for S1 and S3. This higher content may be explained because S2 only grazed on herbs and shrubs, in contrast to S1 and S3 which were additionally supplemented with grain concentrates.

In vivo randomized trial of three marketed milk preparations enriched with calcium and vitamins (D and K) on bone mass and bone turnover markers from biological fluids in premenopausal Caucasian women.

INTRODUCTION: osteoporosis is a metabolic bone disease that leads to increased bone fragility and increased risk of fracture. OBJECTIVES: the aim of the present research was to determine the effectiveness of a diary intake of three different dairy products (250 ml) enriched with vitamins and calcium on decreasing bone mass. METHOS: the present study is a comparative trial of three dairy products fortified with calcium and vitamin D, parallel, randomized, double-blind andsingle-center. Bone mass content (BMC), bone mass density (BMD), T-score and Z-score were measured in different locations, besides biochemical markers along 18 months in premenopausal women. Two hundred and ten volunteers from all the three groups were submitted to the same monitoring procedures, consisting on blood extraction, urine collection and energy X-ray absorptiometry (DEXA) done in the laboratory. The monitoring was carried on three times, first at month 0 (baseline), the second at month 9 (in the middle of the treatment) and, finally, at month 18 (the end of the treatment). RESULTS: the majority of anatomical locations showed both BMC and BMD decrease ranging between 0.5% and 1.5%. The T-score and the Z-scoreincreased in lumbar spine after the treatment with the dairy products. Moreover, the most noteworthy change on the biomarkers of bone resorption was showed by plasmatic tartrate-resistant acid phosphatase (TRAP), with and increase between 20.7% and 29.5% after the intake of the different products. CONCLUSIONS: therefore, the intake of the three dairy products improves the bone mass in lumbar spine, leading to important changes in the concentration of biomarkers of bone resorption. Especially, tartrate-resistant acid phosphatase seems to be strongly influenced by the intake of every dairy product. However, no significant differences were found between the different dairy products used in the present study. Therefore, the intake of dairy product seems to be more determinant than micronutrients supplementation.

Randomized, double-blind study comparing percutaneous electrolysis and dry needling for the management of temporomandibular myofascial pain

BACKGROUND: To assess whether the techniques of percutaneous needle electrolysis (PNE) and deep dry needling (DDN) used on trigger points (TrP) of lateral pterygoid muscle (LPM) can significantly reduce pain and improve function in patients with myofascial pain syndrome (MPS) compared to a control group treated with a sham needling procedure (SNP). MATERIAL AND METHODS: Sixty patients diagnosed with MPS in the LPM were selected and randomly assigned to one of three groups. The PNE group received electrolysis to the LPM via transcutaneous puncture. The DDN group received a deep puncture to the TrP without the introduction of any substance. In the SNP group, pressure was applied to the skin without penetration. Procedures were performed once per week for 3 consecutive weeks. Clinical evaluation was performed before treatment, and on days 28, 42 and 70 after treatment. RESULTS: Statistically significant differences (p < 0.01) were measured for the PNE and DDN groups with respect to pain reduction at rest, during chewing, and for maximum interincisal opening (MIO). Values for the PNE group showed significantly earlier improvement. Differences for PNE and DDN groups with respect to SNP group were significant (p < 0.05) up to day 70. Evaluation of efficacy as reported by the patient and observer was better for PNE and DDN groups. No adverse events were observed for either of the techniques. CONCLUSIONS: PNE and DDN of the LPM showed greater pain reduction efficacy and improved MIO compared to SNP. Improvement was noted earlier in the PNE group than in the DDN group

Early and intermediate age-related macular degeneration: update and clinical review.

Age-related macular degeneration (AMD) is the leading cause of irreversible central vision loss in developed countries. With the aging of population, AMD will become globally an increasingly important and prevalent disease worldwide. It is a complex disease whose etiology is associated with both genetic and environmental risk factors. An extensive decline in the quality of life and progressive need of daily living assistance resulting from AMD among those most severely affected highlights the essential role of preventive strategies, particularly advising patients to quit smoking. In addition, maintaining a healthy diet, controlling other risk factors (such as hypertension, obesity, and atherosclerosis), and the use of nutritional supplements (antioxidants) are recommendable. Genetic testing may be especially important in patients with a family history of AMD. Recently, unifying criteria for the clinical classification of AMD, defining no apparent aging changes; normal aging changes; and early, intermediate, and late AMD stages, are of value in predicting AMD risk of progression and in establishing recommendations for the diagnosis, therapeutic approach, and follow-up of patients. The present review is focused on early and intermediate AMD and presents a description of the clinical characteristics and ophthalmological findings for these stages, together with algorithms for the diagnosis and management of patients, which are easily applicable in daily clinical practice.

La eficacia del tratamiento individual de los acúfenos subjetivos con terapia cognitiva-conductual / The efficacy of individual treatment of subjective tinnitus with cognitive behavioural therapy

Introducción: Los acúfenos subjetivos, a pesar del tiempo transcurrido desde que fueron descritos por primera vez, continúan sin tener un tratamiento con eficacia demostrada. El objetivo de este artículo es valorar la eficacia de la terapia cognitiva-conductual en el tratamiento de estos enfermos. Pacientes y métodos: Durante un periodo de tiempo de los años 2012-2013 se estudia a 310 enfermos que presentaban acúfenos subjetivos. De ellos, 267 fueron incluidos en un tratamiento basado en terapia cognitiva-conductual. El periodo de seguimiento fue de 18 meses y en 11 enfermos de 21 meses. Resultados: Considerando los enfermos que interrumpieron el tratamiento como fracasos, el porcentaje de curación fue de 95,7%. Conclusión: La terapia cognitiva-conductual debe estar siempre incluida en el tratamiento de los enfermos de acúfenos (AU)

Introduction: It has been a long time since subjective tinnitus cases were described for the first time but they still lack a treatment with proven effectiveness. The main goal of this study was to evaluate the effectiveness of cognitive behavioural therapy in these patients. Patients and method: Between 2012 and 2013, 310 patients that suffered from subjective tinnitus were studied. Of these, 267 were included in treatment based on cognitive behavioural therapy. The monitoring period lasted 18 months for most cases, while it lasted 21 months for 11 patients. Results: Considering patients that interrupted their treatment as failures, the percentage of recovery was 95.7%. Conclusion: Cognitive behavioural therapy should always be included in the treatment of people suffering from tinnitus (AU)

[Prevalence of sensitization to allergens in school children with asthma residents from Guadalajara metropolitan area]. / Prevalencia de sensibilización a alergenos en niños escolares con asma que viven en la zona metropolitana de Guadalajara.

BACKGROUND: Allergic sensitization is dependent on the geographical and climatic conditions in each region; therefore, identify agents most commonly sensitized children with asthma is important for planning prevention measures. OBJECTIVE: To determine the prevalence of the sensitization to allergens in children with asthma. MATERIAL AND METHOD: This cross-sectional and prolective study includes children from ages 6 to 14, who have asthma, attended for the first time in an allergy service. The patients were recruited consecutively between the months of January 1st 2014 to December 31st 2014. The frequency of the allergen sensitization was estimated. RESULTS: This study included 186 children, the median age was 7 years olds, the male group was 104/186 (55.9%) The median of the positive results was 5 and monosensitized were 47/186 (2.2%). The most common category of allergens was the indoor (90.3%), then trees (71.0%), and finally the fungi (9.7%). Individually, the house dust mites were more common in between the interior allergens, followed by the epithelial; in the tree pollen were oaks (31.7%) and ashes (28.0%), in weeds was mugwort (21.5%), in grasses was Zea mays (18.3%) and in the fungi was Cladosporium spp. (6.5%). CONCLUSION: The high prevalence of the sensitization to house dust mites and epithelial in children with asthma, stimulates to implement methods of environmental control for contributing a better control of the disease.

Antecedentes: la prevalencia de rinosinusitis crónica en pacientes adultos con inmunodeficiencia común variable (IDCV) es de 52%. Los pacientes con esta enfermedad tienen mayor frecuencia de rinosinusitis crónica, enfermedad inflamatoria que afecta a la mucosa de uno o más senos paranasales y la cavidad nasal. Objetivo: identificar los microorganismos de secreción del meato medio obtenida por endoscopia asociados con rinosinusitis crónica en pacientes adultos con inmunodeficiencia común variable (IDCV). Material y método: estudio descriptivo, transversal, que incluyó a pacientes adultos con inmunodeficiencia común variable, de quienes se obtuvo una muestra vía endoscópica de secreción del meato medio de ambas fosas nasales, que se envió a cultivo para bacterias aerobias, anaerobias y hongos. Se obtuvo consentimiento informado de todos los pacientes. Resultados: se estudiaron 29 pacientes: 18 mujeres y 11 hombres, con edad promedio de 40±13 años. Los resultados obtenidos fueron: 2 muestras de pacientes no tuvieron desarrollo microbiano, 24 tuvieron desarrollo de bacterias aerobias, en 3 casos hubo crecimiento fúngico sin desarrollo de bacterias anaerobias. Conclusiones: nuestros resultados muestran que los microorganismos asociados con rinosinusitis crónica en pacientes adultos con inmunodeficiencia común variable más comunes son: Moraxella catarrhalis, Staphylococcus, Sphingomonas paucimobilis y Citrobacter koseri; los agentes micóticos asociados fueron: Candida albicans y Aspergillus fumigatus.
