Cheese whey and dairy manure anaerobic co-digestion at psychrophilic conditions: Technical and environmental evaluation.

Cheese whey (CW) and dairy manure (DM) are the main residues from the dairy industry, both of which can led to significant negative environment impacts if not properly managed. However, their combined anaerobic digestion represents an opportunity to obtain bioenergy and a stabilised material as a soil improver on the farm. Biochemical potential of methane (BMP) assays were carried out at psychrophilic conditions (20 °C) to analyse the influence on biomethane production of different CW:DM mixtures (% w/w) at different of inoculum-to-substrate ratios (ISR). Based on the BMP results, a life cycle assessment (LCA) of the cheese manufacturing process was carried out considering two scenarios (i) considering the current process, where propane gas and electricity are used for cheese production (ii) the incorporation of the biogas generated in the cheese production process in the company. BMP results showed that the best mixture between CW and DM was 65:35 (weight basis) at an organic load of 0.6 gVS/L (ISR of X). The LCA showed that CW and DM anaerobic digestion allowed to reduce the cheese manufacturing carbon footprint from through the substitution of propane by the biogas produced, changing from 5.5 to 3.1 kg CO2-eq/kg cheese produced, which indicates that according to the monthly production (633.6 kg) it would stop emitting about 1519 kg CO2-eq, i.e. a saving in terms of emissions of approximately 43,6% of the total currently generated.

Magnetic-Assisted Reduced-Port Sleeve Gastrectomy Versus Laparoscopic Sleeve Gastrectomy: a Comparative Study.

BACKGROUND: Sleeve gastrectomy is one of the most popular bariatric surgeries. With the advent of new technologies, a reduced-port approach assisted by magnets for sleeve gastrectomy (RPSG-MA) has been developed. The aim of our study is to compare the short-term results of RPSG-MA vs conventional laparoscopic SG (CLSG). METHODS: A comparative study was performed. We compared two groups who underwent RPSG-MA (n=150) and CLSG (n=135) between January 2020 and January 2022. RESULTS: Both groups were similar in body mass index, age, sex, and type of comorbidities. The operative time was similar in both groups (RPSG-MA, 52.5 min vs CLSG, 52.9 min; p = 0.829). Length of hospital (1.07 days) stay was significantly shorter in the RPSG-MA group (p = 0.00) than in the CLSG group (1.51 days). There were no conversions to open surgery in any patient or any fatal event. Complications encountered were similar in both groups postoperative. There were minor adverse events directly related to the magnetic device in 3 cases, these being mild hepatic lacerations, resolved with hemostatic measures. CONCLUSION: The magnet-assisted reduced-port gastric sleeve compared to the conventional technique has proven to be safe, technically feasible and with multiple benefits.

Life cycle inventory data for ethyl levulinate production from Colombian rice straw.

This data article is associated with the research article "Sustainable production of ethyl levulinate by levulinic acid esterification obtained from Colombian rice straw". This paper shows the methodology to calculate the Life Cycle Inventory (LCI) of the foreground system to perform the Life Cycle Assessment (LCA) of the ethyl levulinate (EL) production from Colombian rice straw (RS). This process encompasses two main stages: (i) RS production (involving cultivation and harvesting) and (ii) EL production (involving acid hydrolysis, levulinic acid (LA) purification, and El production). On one hand, foreground data related to paddy rice cultivation was gathered from the literature review. Besides, emissions of the cultivation stage were calculated using the IPCC (Intergovernmental Panel on Climate Change) methodology. The SQCB (Sustainable Quick Check for Biofuels) methodology was used to calculate NH3, NOx, N2O and NO3 emissions, whereas the SALCA (Swiss Agricultural Life Cycle Assessment) model was used to calculate phosphorous emissions to water. The Turc method was employed to calculate the irrigation requirements based on the rainfall and agrological features of rice culture. On the other hand, foreground data related to RS conversion to EL within a biorefinery scheme was obtained from simulation using Aspen Plus v.12. Lastly, background data associated with raw materials, catalysts, and utilities were gathered from Ecoinvent database. All the inventories are meaningful to carry out future environmental assessments involving sustainable production processes using RS as raw material or biorefinery processes using dilute acid hydrolysis.

A Randomized, Controlled Trial of Trifarotene Plus Doxycycline for Severe Acne Vulgaris.

Objective: We evaluated the efficacy and safety of trifarotene plus oral doxycycline in acne. Methods: This was a randomized (2:1 ratio) 12-week, double-blind study of once-daily trifarotene cream 50µg/g plus enteric-coated doxycycline 120mg (T+D) versus trifarotene vehicle and doxycycline placebo (V+P). Patients were aged 12 years or older with severe facial acne (≥20 inflammatory lesions, 30 to 120 non-inflammatory lesions, and ≤4 nodules). Efficacy outcomes included change from baseline in lesion counts and success (score of 0/1 with ≥2 grade improvement) on investigator global assessment (IGA). Safety was assessed by adverse events and local tolerability. Results: The study enrolled 133 subjects in the T+D group and 69 subjects in the V+P group. The population was balanced, with an approximately even ratio of adolescent (12-17 years) and adult (≥18 years) subjects. The absolute change in lesion counts from baseline were: -69.1 T+D versus -48.1 V+P for total lesions, -29.4 T+D versus -19.5 V+P for inflammatory lesions, and -39.5 T+D versus -28.2 for non-inflammatory lesions (P<0.0001 for all). Success was achieved by 31.7 percent of subjects in the T+D group versus 15.8 percent in the V+P group (P=0.0107). The safety and tolerability profiles were comparable between the T+D and V+P arms. Conclusion: T+D was demonstrated to be safe and efficacious as a treatment option for patients with severe acne.

Dermatologic manifestations in patients with the Hermansky-Pudlak syndrome types 1 and 3.

BACKGROUND: The Hermansky-Pudlak syndrome (HPS) is a genetically heterogeneous group of diseases characterized by oculocutaneous albinism, bleeding diathesis, and systemic complications. It is the most common genetic disorder in Puerto Rico. These patients are at a significant risk of developing a variety of skin complications and little is known about the prevalence of dermatologic diagnoses in this population. OBJECTIVES: To report dermatologic manifestations in patients with Hermansky-Pudlak syndrome (HPS). Secondary aims include skin concerns, sun protection habits, barriers to dermatologic care, and skin cancer knowledge. METHODS: Cross-sectional study with twenty-nine Puerto Rican patients who carried a clinical diagnosis of HPS type 1 or type 3 through a telephonic questionnaire. RESULTS: Twenty-nine patients participated with a mean (SD) age of 37.3 (16.8) years and the majority were female (69%). The most common diagnoses were skin cancer (34.5%), acne (34.5%), bacterial skin infections (34.5%), warts (24%), urticaria (17.2%), and psoriasis (17.2%). The most common skin concerns were dry skin (62.1%), hair loss (58.9%), redness (34.5%), moles (31%), and rash (31%). The most common sun protection behavior was wearing a shirt that covers the shoulders (93.1%, often or always) and the least common was wearing a hat (24.1%, often or always). Higher income was significantly associated with being more likely to use sunscreen often or always (OR = 3.38, 95% CI 1.02-11.18, p = 0.04). Those in northern urban areas were significantly less likely to report barriers to dermatologic care (OR = 0.13, 95% CI 0.02-0.76, p = 0.02). CONCLUSIONS: This study provides an important overview of the most common self-reported skin manifestations in patients with HPS. Unfortunately, a high prevalence of cutaneous malignancy was reported. The results stress the need for adequate care and potential interventions to promote sun protection behaviors and skin cancer prevention.

Estado de salud de personas inmigrantes en Cataluña desde una perspectiva de género: proyecto PELFI / Health status among immigrant in Catalonia from a gender perspective: PELFI project

Objetivo: Evaluar el estado de salud de hombres y mujeres inmigrantes extracomunitarios residentes en el Área Metropolitana de Barcelona (Cataluña, España) e identificar determinantes sociales de la salud desde una perspectiva de género. Método: Análisis transversal de una cohorte de familias inmigrantes reclutadas en Badalona y Santa Coloma de Gramenet (cohorte PELFI). En 2015-2016, 167 inmigrantes respondieron al cuestionario epidemiológico basal y al instrumento EuroQol de cinco dimensiones (EQ-5D) que mide el estado de salud. Para identificar determinantes de la salud se construyeron modelos Tobit con el índice EQ-5D. Resultados: Las mujeres declararon una peor salud percibida (p=0,005). Tener una enfermedad diagnosticada se asoció con una peor percepción de la salud en los hombres (p<0,05). El tiempo de estancia y las cargas familiares, en especial la doble jornada de trabajo, empeoraron la salud percibida de las mujeres. En el modelo ajustado por variables demográficas y determinantes sociales, la situación administrativa estable (−0.136; p=0,015) y el apoyo social (0,182; p=0,02) se asociaron con el índice EQ-5D en ambos sexos. Estar ocupado se asoció a mejor salud en los hombres. Conclusiones: Las personas inmigrantes extracomunitarias residentes en el Área Metropolitana de Barcelona son una población vulnerable y presentan desigualdades en salud por sexo. El apoyo social y la ocupación son factores clave de su estado de salud. Las intervenciones para reducir las vulnerabilidades y desigualdades en salud de las personas inmigrantes deberían promover su inclusión y cohesión social, e incorporar la perspectiva de género. (AU)

Objective: The objective of the study is to assess the health status of immigrant men and women from non-EU countries living in the Metropolitan Area of Barcelona (Catalonia, Spain) and to identify the social determinants of health from a gender perspective. Method: Cross-sectional analysis from a cohort of immigrant families recruited in Badalona and Santa Coloma de Gramenet, in Spain (PELFI cohort). In 2015-2016, 167 immigrants answered the baseline epidemiological questionnaire and the 5-level EuroQol instrument (EQ-5D) which measures health status. To identify health determinants, Tobit models were constructed to the EQ-5D index. Results: Women rated poorer self-perceived health (p=0.005). To be diagnosed with and illness was only associated with poor self-perceived health among men (p<0.05). Length of residence, domestic work, and especially double workload deteriorated women's health. After adjusting models by demographics and social determinants, permanent administrative status (−0.136; p=0.015) and social support (0.182; p=0.02) were associated with health status in both sexes. To have a job was associated with better health only in men. Conclusions: Non-EU immigrants living in the Metropolitan Area of Barcelona are a socially vulnerable group of population and present inequalities in health by sex. Social support and occupation are key factors of their health status. Interventions to reduce immigrant vulnerabilities and inequalities in health should promote their social inclusion and cohesion from a gender perspective. (AU)

[Analysis of ageism during the pandemic, a global elder abuse]. / Análisis del edadismo durante la pandemia, un maltrato global hacia las personas mayores.

Ageism is a form of abuse which has negative influence on elderly people. Although COVID-19 affects people of all ages, it has increased ageism effects, reducing the access of the elderly to different resources, including health system. Ageism is associated to cost overruns, poorer health and early mortality. From «GdT atención al mayor de semFYC¼ we make a series of proposals to decrease it based on community activities that favour intergenerational relationships and ageing education allowing a correct integration of the elderly on society.

Análisis del edadismo durante la pandemia, un maltrato global hacia las personas mayores / Analysis of ageism during the pandemic, a global elder abuse

El edadismo es una forma de maltrato que tiene influencia negativa en las personas mayores. Aunque la COVID-19 afecta a personas de todos los grupos de edad, ha incrementado el efecto del mismo, limita el acceso de los mayores a diversos recursos, entre ellos, los sanitarios. El edadismo se asocia con sobrecostes, con peor salud y mortalidad precoz. Desde el «Grupo de Trabajo (GdT) de Atención al Mayor de la Sociedad Española de Medicina de Familia y Comunitaria (semFYC)» realizamos una serie de propuestas para combatirlo basándonos en actividades comunitarias que favorezcan las relaciones intergeneracionales y la educación en envejecimiento que permitan una correcta integración de los mayores en la sociedad.(AU)

Hybrid revisional surgery: biliary limb distalization plus endoscopic transoral outlet reduction (eTOR).

Roux-en-Y gastric bypass (RYGB) is one of the best procedures for the treatment of obesity and associated comorbidities. However, the percent of revisional procedures after a gastric bypass by weight regain has been increased, therefore several surgical options are available for the treatment of weight regain. In this case report, we combined a biliary limb distalization with endoscopic transoral outlet reduction (eTOR). The purpose of this case report is to expose the viability to perform combined procedures such as the distalization of the biliopancreatic limb plus eTOR increasing malabsorptive and restrictive components that would represent a secure and efficient weight loss in our patient. We could demonstrate the technical feasibility of the combination of both procedures to increase the restrictive and malabsorptive components at the same time with a low-risk range.

An Unusual Case of Deep Localized Scleroderma in a Patient with Chronic Kidney Disease.

Localized scleroderma (LS) is a rare fibrosing disorder of skin and underlying tissues. Although it can affect all races, it has a higher prevalence in whites. Deep LS is the least common among seven LS variants, representing less than 5% of cases, and typically affects areas of pressure such as the hips and waist. We report a unique clinical case of bilateral lower extremity deep LS in a 51-year-old Puerto Rican woman with chronic kidney disease (CKD). In patients with CKD, it is important to distinguish LS from nephrogenic systemic fibrosis (NSF). Both can present with skin fibrosis and contractures over joints yet have significantly differing treatment approaches and prognosis. Our case report is unique due to the patient's Puerto Rican ethnicity, CKD history, and isolated anterior lower extremity involvement. In this report, we highlight key clinical and histopathological findings of LS, and how they differ from that of NSF.

Soledad y envejecimiento / Loneliness and ageing

El objetivo del estudio es conocer la prevalencia de soledad y aislamiento social en mayores de 65 años en Ourense y sus factores asociados. Métodos: estudio descriptivo trasversal, muestra aleatoria de personas mayores de 65 años a las que se realizó una entrevista entre junio de 2010 y junio de 2011. Tamaño muestral: 486 pacientes (soledad estimada del 35%). Se administró la escala OARS-MFAQ (Olders American Resource and Services Multidimensional Functional Assessment Questionnaire), que recoge variables sociodemográficas, recursos sociales, económicos, salud física, mental y la capacidad para llevar a cabo actividades básicas de la vida diaria (ABVD) y actividades instrumentales de la vida diaria (AIVD). Se les hizo la pregunta «¿Se encuentra usted sola/solo?», con cuatro posibles respuestas: siempre, a menudo, casi nunca, nunca. Resultados: se entrevistó a 572 personas de una edad media de 79 años (desviación estándar [DE]: 6,79). Soledad: 32,7%; vive sola/solo: 17%; sin contacto semanal: 18,9%; aislamiento social: 1,4%. Fueron factores asociados a la percepción de soledad: ser mujer, tener pensión y nivel educativo bajos, depresión, deterioro cognitivo, pérdida de visión, dependencia para las AVBD, tomar psicofármacos en los 6 meses previos y la necesidad de mejoras en la vivienda. La práctica de ejercicio regular constituyó un factor protector. Conclusiones: la soledad en nuestra población es similar a la descrita en otros ámbitos, se asocia a desigualdad de género, factores sociales y demográficos, depresión y deterioro cognitivo. Los profesionales de Atención Primaria deben identificarla y abordarla.(AU)

The aim of this research is to ascertain the prevalence of loneliness and social isolation in people aged over 65 in Ourense and its associated factors. Methods: descriptive cross-sectional study, random sample of people aged over 65 interviewed between June 2010 and June 2011. Sample size was 486 patients (estimated loneliness 35%). The OARS (Olders American Resource and Services Multidimensional Functional Assessment Questionnaire) scale was administrated. This includes sociodemo-graphic variables, socio-economic resources, physical and mental health and the ability to undergo BADL and IADL. The question “are you alone?” with four possible answers was also posed. Results: a total of 572 people were interviewed, aged on average 79 years old (SD: 6.79). Loneliness 32.7%; living alone 17.0%; no weekly contacts 18.9%; social isolation (living alone + no contacts) 1.4%. Feelings of loneliness were associated with sex (women), low pension and educational level, depression, cognitive impairment, vision loss, dependence for BADL, psychopharmacological treatment in the previous six months and the need for home improvements. Regular physical exercise was a protective factor. Conclusions: loneliness in our population is similar to the one reported in other areas. It is associated with sex inequalities, social and demographic factors, depression and cognitive impairment. Primary care professionals need to identify and tackle loneliness.(AU)

Magnetic device in reduced port and single port bariatric surgery: First 170 cases experience.

INTRODUCTION: Magnetic devices have been successfully used in bariatric surgery. To the date, the only reported use of the magnet was for liver retraction. Our purpose in this study is to demonstrate the safety and viability of using a magnetic system in different steps in single port and reduced port bariatric surgery. METHODS: Prospective and observational study was performed. Patients older than 18 years, undergoing primary laparoscopic sleeve gastrectomy (SG), one-anastomosis gastric bypass (OAGB), and Roux-en-Y gastric bypass (RYGB) or revisional surgery by single-port or reduced-port approach between July 2020 and June 2021 were included. RESULTS: A total of 170 patients (mean BMI, 41.47kg/m2; mean age 36.92 yrs) completed laparoscopic bariatric surgery (54 single-port sleeve gastrectomy [SPSG], 16 reduced-port SG, 83 RYGB, 4 OAGB and 14 revision surgeries), using the magnetic surgical system in different steps of the surgery. Mean surgical time for SPSG and reduced-port SG was 65.52min and 59.36min respectively; and for RYGB 74.19min, OAGB 70.98min, and revisional surgeries 88.38min. As for intraoperative complications, 2.94% mild liver laceration without significant bleeding was reported. There were no 30-day mortalities and no major complications. CONCLUSION: Magnetic assistance in single-port and reduced-port bariatric surgery is an innovative technique. With this prospective study we attempt to demonstrate the safety profile and potential uses that may improve the implementation of new surgical approaches in bariatric surgery.

The more diseases, the more consumption of drugs, without relation between potentially inappropriate prescriptions and the epidemiological and clinical characteristics of the patients. Conclusions: STOPP-START criteria are useful for reviewing prescription in people over 65 with cardiovascular disease among their pluripatology (AU)

Environmental and economic analysis of bioethanol production from sugarcane molasses and agave juice.

In this article, sugarcane molasses and agave juice were compared as potential feedstocks for producing bioethanol in Mexico in terms of their environmental impact and economic factors. Life cycle assessment (LCA) using SimaPro was carried out to calculate environmental impacts by using a cradle-to-gate approach. A preliminary economic analysis was performed to determine the economic feasibility of the studied options. Also, capital goods costs were obtained using the Aspen Plus economy package. Moreover, a sensitivity analysis was involved to compare the environmental and economic viability of producing bioethanol from sugarcane molasses and agave juice. LCA results revealed that cultivation and fermentation were the most harmful stages when producing bioethanol from sugarcane molasses and agave juice, respectively. Furthermore, when it was derived from agave juice rather than sugarcane molasses, it had more environmental benefits. This was ascribed to the lower consumption rate of fertilizers, pesticides, and emissions given off from the former. Regarding financial aspects, the preliminary analysis showed that producing bioethanol was not economically viable when grid energy alone was used. However, if power from the grid is partially replaced with renewable energy, producing bioethanol becomes economically feasible, and sugarcane molasses is the most suitable feedstock.

Life cycle inventory data for power production from sugarcane press-mud.

This data article is associated with the research article "Technical and environmental analysis on the power production from residual biomass using hydrogen as energy vector". This paper shows the procedure to calculate the Life Cycle Inventory (LCI) of the foreground system to perform the Life Cycle Assessment (LCA) of the power production from sugarcane press-mud. Said process encompasses four main stages: i) bioethanol production; ii) bioethanol purification; iii) syngas production and purification; and iv) power production. Additionally, other processes such as biomethane production and manufacturing of catalyst were included. Foreground data related to bioethanol production was gathered from experimental procedures at lab-scale. While foreground data, concerning the other processes such as bioethanol purification, syngas production and purification, power production, and biomethane production, was built by using material and energy flows obtained from Aspen Plus®. Lastly, LCI of the catalyst manufacturing was built based on literature review and the approach stated by Ecoinvent. All the inventories are meaningful to carry out future environmental assessments involving sustainable energy systems based on bioethanol, biomethane, or hydrogen.

Mental well-being of the general population: direct and indirect effects of socioeconomic, relational and health factors.

PURPOSE: The aim of this study was to analyse the association between individual mental well-being and social, economic, lifestyle and health factors. METHODS: Cross-sectional study on a representative sample of 13,632 participants (> 15y/o) from the Catalan Health Interview Survey 2013-2016 editions. Mental well-being was assessed with the Warwick-Edinburg Mental Well-being Scale (WEMWBS). Linear regressions were fitted to associate well-being and sociodemographic, relational, lifestyle and health variables according to minimally sufficient adjustment sets identified using directed acyclic graphs. Predictors entered the model in blocks of variable types and analysed individually. Direct and total effects were estimated. RESULTS: Health factors significantly contributed to mental well-being variance. Presence of a mental disorder and self-reported health had the largest effect size (eta2 = 13.4% and 16.3%). The higher individual impact from a variable came from social support (ß = - 12.8, SE = 0.48, eta2 = 6.3%). A noticeable effect gradient (eta2 = 4.2%) from low to high mental well-being emerged according to economic difficulties (from ß = 1.59, SE = 0.33 for moderate difficulties to ß = 6.02 SE = 0.55 for no difficulties). Younger age (ß = 5.21, SE = 0.26, eta2 = 3.4%) and being men (ß = 1.32, SE = 0.15, eta2 = 0.6%) were associated with better mental well-being. Direct gender effects were negligible. CONCLUSIONS: This study highlights health and social support as the most associated factors with individual mental well-being over socioeconomic factors. Interventions and policies aimed to these factors for health promotion would improve population mental well-being.
