Residual formaldehyde contents in fresh white cheese in El Salvador: Seasonal changes associated with temperature.

Detection of residual formaldehyde (FA) in dairy products could be explained by direct addition of this preservative to extend the shelf life of raw material or final product at room temperature. FA is not authorized as a preservative by international standards and its addition to dairy products is prohibited due to its potentially harmful effects on consumers. Although the carcinogenicity of FA by oral exposure has not been proven, it is also known it cause histopathological and cytogenic changes in tissues at first contact, so its toxicity by ingestion should not be underestimated. This research determined both residual FA levels in locally produced fresh white cheese and its variation according to the seasons of the year and its association with ambient temperature. None of the FA levels quantified in cheese exceeded the maximum tolerable concentration (2.6 mg/kg) and although average FA contents did not vary significantly with seasonal changes (0.093-0.181 mg/kg), the number of positive cases did, since the highest prevalence occurred in the dry (60.9 %) and transitional dry-rainy (79.7 %) seasons of 2021, which are characterized by having the highest average ambient temperatures (27.5 °C and 28.3 °C, respectively). It was also shown that 79.6 % of the variability of FA-positive samples is explained by changes in the average temperature according to the year´s season. The association between these variables and quantified levels of aldehyde in raw milk sampled at the plant could indicate that FA was used to prevent milk and/or the final product from decomposing due to the effect of high ambient temperature. In addition, residual FA contents decreased in both milk and cheese, depending on added preservative levels, and the time elapsed prior to analysis.

Okra (Abelmoschus esculentus) in a refugee context in East Africa: Kitchen gardening helps with mineral provision.

Kitchen gardening is considered a way to reconnect with agriculture and complement the cereal-based relief food offered to refugees in East Africa. This work aimed at profiling mineral content of okra in four refugee camps and settlements located in Ethiopia and Uganda and its contribution to adequate intake (AIs) or recommended dietary allowances (RDAs) for young children and pregnant and lactating women (PLW). The study also evaluated the applicability of portable X-ray fluorescence (PXRF) as compared with inductively coupled plasma mass spectrometry (ICP-MS) for mineral profiling of okra powder samples. The contents of minerals (mg kg-1) from the ICP-MS readings were in the following ranges: K (14,385-33,294), Ca (2610-14,090), P (3178-13,248), Mg (3896-7986), Cu (3.81-19.3), Fe (75.7-1243), Zn (33-141) and Mn (23.1-261). Regardless of geographic origin, at low-end consumption probability (17 g day-1 for young children and 68 g day-1 for PLW), okra could contribute ˂ 15% (2.7-12.9%) AI for macro-minerals (K and Ca). In addition, the contributions to RDA values for Fe and Zn, elements of known public health interest, ranged from 4.5 to 34.7% for young children. Interestingly, regression lines revealed strong agreement between ICP-MS and PXRF readings for Mn and Zn, with R2 values > 0.91. This information is useful in support of nutrition-sensitive kitchen gardening programs through scaling culturally important crops in refugee settings.

Source identification of n-alkanes and isoprenoids using diagnostic ratios and carbon isotopic composition on crude oils and surface waters from the Gulf of Mexico.

Diagnostic ratios and compound-specific isotopic analysis (CSIA) are two tools that can help identify and differentiate the petrogenic and biogenic sources of hydrocarbons found in environmental samples. The present study aims to evaluate the concentration and type of n-alkanes and isoprenoids found in the oligotrophic waters of the Gulf of Mexico (n = 14), and through the typical diagnostic ratios reported for n-alkanes and its carbon isotopic composition (δ13C) to establish and differentiate the possible source of the hydrocarbons. Additionally, crude oil samples (n = 10) extracted in the Gulf of Mexico were evaluated by CSIA as a possible source of hydrocarbons to the study area. We found that the CSIA of δ13C for n-alkanes (n-C11 to n-C30) and isoprenoids (pristane and phytane) found in the surface water samples varied from - 25.55 to - 37.59‰ and from - 23.78 to - 33.97‰ in the crude oil samples, values which are more related to petrogenic sources. An analysis of the δ13C for pristane vs. phytane suggests that only three surface water samples show an origin in common that those observed in crude oils of the Gulf of Mexico. A low incidence of odd- and even-numbered n-alkanes higher than n-C25 in the water samples indicate low to negligible presence of terrigenous sources into the area, which was supported by the carbon isotopic composition of the individual n-alkanes.

Preoperative Trapped Lung Is Associated With Increased Mortality After Orthotopic Liver Transplantation.

INTRODUCTION: Trapped lung, characterized by atelectatic lung unable to reexpand and fill the thoracic cavity due to a restricting fibrous visceral pleural peel, is occasionally seen in patients with end-stage liver disease complicated by hepatic hydrothorax. Limited data suggest that trapped lung prior to orthotopic liver transplantation may be associated with poor outcomes. RESEARCH QUESTION: What is the clinical significance of trapped lung in patients receiving orthotopic liver transplantation? DESIGN: We performed a retrospective analysis of patients who underwent liver transplantation over an 8-year period. Baseline clinical characteristics and postoperative outcomes of adult patients with trapped lung were analyzed and compared to the overall cohort of liver transplant recipients and controls matched 3:1 based on age, sex, Model for End-Stage Liver Disease (MELD) score, and presence of pleural effusion. RESULTS: Of the 1193 patients who underwent liver transplantation, we identified 20 patients (1.68%) with trapped lung. The probability of 1 and 2-year survival were 75.0% and 57.1%, compared to 85.6% and 80.4% (p = 0.02) in all liver transplant recipients and 87.9% and 81.1% (p = 0.03) in matched controls respectively. Patients with trapped lung had a longer hospital length of stay compared to the total liver transplant population (geometric mean 54.9 ± 8.4 vs. 27.2 ± 0.7 days, p ≤ 0.001), when adjusted for age and MELD score. DISCUSSION: Patients with trapped prior to orthotopic liver transplantation have increased probability of mortality as well as increased health care utilization. This is a small retrospective analysis, and further prospective investigation is warranted.

Obesity and smoking as risk factors for invasive mechanical ventilation in COVID-19: A retrospective, observational cohort study.

PURPOSE: To describe the trajectory of respiratory failure in COVID-19 and explore factors associated with risk of invasive mechanical ventilation (IMV). MATERIALS AND METHODS: A retrospective, observational cohort study of 112 inpatient adults diagnosed with COVID-19 between March 12 and April 16, 2020. Data were manually extracted from electronic medical records. Multivariable and Univariable regression were used to evaluate association between baseline characteristics, initial serum markers and the outcome of IMV. RESULTS: Our cohort had median age of 61 (IQR 45-74) and was 66% male. In-hospital mortality was 6% (7/112). ICU mortality was 12.8% (6/47), and 18% (5/28) for those requiring IMV. Obesity (OR 5.82, CI 1.74-19.48), former (OR 8.06, CI 1.51-43.06) and current smoking status (OR 10.33, CI 1.43-74.67) were associated with IMV after adjusting for age, sex, and high prevalence comorbidities by multivariable analysis. Initial absolute lymphocyte count (OR 0.33, CI 0.11-0.96), procalcitonin (OR 1.27, CI 1.02-1.57), IL-6 (OR 1.17, CI 1.03-1.33), ferritin (OR 1.05, CI 1.005-1.11), LDH (OR 1.57, 95% CI 1.13-2.17) and CRP (OR 1.13, CI 1.06-1.21), were associated with IMV by univariate analysis. CONCLUSIONS: Obesity, smoking history, and elevated inflammatory markers were associated with increased need for IMV in patients with COVID-19.

Aflatoxin M1 in Nicaraguan and locally made hard white cheeses marketed in El Salvador.

Aflatoxin M1 is a carcinogenic and genotoxic metabolite of Aflatoxins present in food contaminated by fungi for lactating cattle, it is excreted through milk and when used to make cheese, the toxin will also be transferred to the dairy. The contamination of unripened hard white cheese with AFM1 seems to vary according to the season of the year, possibly due to the change of foodstuff, from fresh pasture in the rainy season to dried foods in the dry season and vice versa. This research determined both the prevalence and contents of AFM1 in cheeses of local and Nicaraguan origin marketed in El Salvador, as well as the changes occurred according to the season and the association between levels of AFM1 with meteorological parameters. The significantly higher prevalence of AFM1 contamination in both local cheeses and Nicaraguans, was found in the dry season and the lowest in the rainy season (41 % vs. 20 %; 31 % vs. 0%, respectively), the same trend was observed in AFM1 contents (0.076 vs. 0.036 µg/kg; 0.050 vs. 0.021 µg/kg, respectively). A significant association was demonstrated between levels of AFM1 with the averages of accumulated rainfall and relative humidity according to the sampled season. The prevalence of AFM1 in cheeses indicate that El Salvador and Nicaragua are endemic to dairy contamination by that mycotoxin. Seasonal variation may be due to a lack of rainfall, that promotes the growth of aflatoxigenic fungi in the crops of raw materials, which will be used for feedstuff intended for dairy cattle, thus, the consumption of contaminated food will cause the temporary increase of AFM1 in milk and their derivatives.

Alpha-1 Antitrypsin Deficiency: a Rare Disease?

PURPOSE OF REVIEW: Commonly categorized as a rare disease, alpha-1 antitrypsin deficiency (AATD) is neither rare, when compared to many other genetic disorders, nor an actual disease, but rather a predisposition toward a wide variety of diseases. It is one of the most common genetic disorders which can lead to a spectrum of clinical manifestations, ranging from no symptoms to progressively debilitating systemic disease, most commonly affecting the lung and liver. It is therefore imperative for clinicians to recognize and be familiar with the spectrum of presentations, methods of diagnosis, and clinical management of AATD. It is also imperative for scientists to recognize the potential for progress in the management of this disorder. RECENT FINDINGS: This review focuses on the current state of knowledge of AATD, including the wide range of presentations, diagnosis, and clinical management. In addition to the clinical implications of severe AATD, we discuss the relevance of heterozygous state with mild or moderate AATD in the development of both lung and liver disease. While our understanding of the multiple roles of alpha-1 antitrypsin (AAT) is on the rise, with appreciation of its immunomodulatory, anti-infective, and anti-inflammatory properties, this knowledge has yet to impact our ability to predict outcomes. We discuss nuances of augmentation therapy and review novel therapeutic approaches currently under investigation. With the expanding knowledge about the complexities of AAT function and its clinical relevance, and with the increasing ability to diagnose early and intervene on AATD, it should be our goal to change the perception of AATD as a correctable inherited disorder rather than a fatal disease.

Perioperative Considerations in Liver Transplantation.

Liver transplantation (LT) has the potential to cure patients with acute and chronic liver failure as well as a number of hepatic and biliary malignancies. Over time, due to the increasing demand for organs as well as improvements in the survival of LT recipients, patients awaiting LT have become sicker, and often undergo the procedure while critically ill. This trend has made the process of preoperative assessment and planning, intraoperative management, and postoperative management even more crucial to the success of LT programs. Multidisciplinary and specialized teams are essential and include anesthesiologists, surgeons, and intensivists. This article focuses on the preoperative evaluation, intraoperative care, and postoperative management of the liver transplant patient. Management relevant to the critically ill patient is discussed, with a focus on the management of postoperative cardiopulmonary conditions including the care of special populations such as those with hepatopulmonary syndrome and portopulmonary hypertension.

The Merete BioBall system in hip revision surgery: A systematic review.

BACKGROUND: Modular hip arthroplasty is widely recognized in hip surgery; nevertheless, despite advances in prosthetic design, the incidence of hip revision surgery is increasing. In these procedures, a modular adapter that engages the femoral stem and the modular femoral head could be useful in order to protect the neck-head junction and restore preoperative biomechanics and soft tissue tension when the femoral or acetabular component should be retained. The Merete™ BioBall™ system (Merete Medical, Berlin, Germany) could fill this need. However the literature regarding this device is sparse, therefore we performed a systematic review to analyze: the indications for its use and clinical results and the causes of second revision and survival in hip revision surgery, mainly focus in complications of its use. MATERIALS AND METHODS: Databases including PubMed and Google Scholar were searched for English-language articles published between 01/01/1999 and 01/04/2017, using search terms related to the system Merete™ BioBall™. Studies that reported the clinical use of the Merete™ BioBall™ system in hip revision surgery were selected. Data related to the indications, characteristics of the implant, clinical results, causes of second revision and survival were gathered. RESULTS: A total of 14 studies with a level IV evidence were analyzed. Information related to the implant was provided in 194 cases. Isolated acetabular revision was the main indication of implant use (139/194 [71.6%]). The most common combination used was the standard implant (69/110 specified [59.4%]), 3XL length (28/107 specified [26.2%]) with 32mm metal head (58/187 specified [31%]). After a follow-up ranging from 2 to 97 months, there were 16 complications, thirteen (81,2%) were revised, including one neck fracture of the stem (6.25%), two ceramic head fractures (12,5%) and six recurrent dislocations (37,5%). Implant survival was 92.8% at 52.5 months of follow-up in the longest published series. Clinical and functional results were provided in a heterogeneous way. CONCLUSIONS: There is insufficient evidence to recommend for or contraindicate the use of the Merete™ BioBall™ system. The Isolated acetabular revision was the main indication of implant use. When dislocation is the indication of its use the rate of second revision is high. Some important complications possibly related with the implant design have been reported but as isolated cases. The neck adapter failure or corrosion phenomena have not been reported. Further prospective and controlled trials are needed to assess the use of this type of implant and its survival. LEVEL OF EVIDENCE: Level III systematic review of case series.

Occurrence of Aflatoxin M1 in cow milk in El Salvador: Results from a two-year survey.

Aflatoxin M1 (AFM1) is a metabolite of Aflatoxin B1 (AFB1) and is excreted through cow´s milk. AFM1 contamination of milk is extended geographically and there might be seasons-related variations for both prevalence and contents, with higher than average values in regions with long periods of drought like El Salvador. Therefore, this project quantified AFM1 levels in raw cow milk and AFs in cattle feedstuffs, during the transitional dry-rainy seasons of two consecutive years and it determined the variation of occurrence and contents associated to drought. Significant variations were shown from year to year in the prevalence of contamination (30% vs. 20%) and in the average levels of AFM1 in milk (0.056 vs 0.039 µg/kg), associated with drought and increased temperature. The AFs median levels raised significantly with the drought period (from 22.5 to 10.3 µg/kg). A significant relationship was demonstrated between AFs levels and those of AFM1, both in the year with drought and without that condition. AFM1 positive cases and its levels in milk increase in drought and hot conditions, AFs levels in the cattle feed tend to be higher with the same, as well. Both relationship between AFs and AFM1 levels and their association with drought were demonstrated. So that, heat and drought stress conditions can evoke raising effects on both Aflatoxins level and occurrence due to AFM1 in milk is a carryover from AFs contaminated feedstuffs ingested by dairy cows.

[Autoimmune hepatitis induced by isotretionine]. / Hepatitis autoinmune inducida por isotretionina.

We describe a case of a teenage patient with the diagnosis of drug induced autoimmune hepatitis. The patient is a 16 years old female, with the past medical history of Hashimoto’s hypothyroidism controlled with levothyroxine, who started treatment with Isotretionin (®Accutane) 20 mg q/12 hours for a total of 3 months for the treatment of severe acne. The physical examination was within normal limits and the results of the laboratory exams are: Baseline values of ALT 28 U/L, AST 28 U/L. Three months later: AST 756 U/L, ALT 1199U/L, alkaline phosphatase 114 U/L, with normal bilirrubin levels throughout the process. The serology studies were negative for all viral hepatitis; ANA titers were positive (1/160) and igG levels were also elevated. A liver biopsy was performed, and was compatible with the diagnosis of autoimmune hepatitis. Corticosteroid therapy was started with Prednisone 40 mg per day one week after stopping the treatment with isotretionin, observing an improvement in the laboratory values. We describe this case and review the world literature since there are no reported cases of Isotretinoin-induced autoimmune hepatitis.

[Validation of the Rockall score in elderly patients with non variceal upper gastrointestinal bleeding in a third level general hospital]. / Validación del score de Rockall en pacientes adultos mayores con hemorragia digestiva alta no variceal en un hospital general de tercer nivel.

OBJECTIVE: To validate the Rockall score in elderly patients with non variceal upper gastrointestinal bleeding, in terms of mortality and recurrent bleeding at 30 days follow-up. MATERIAL AND METHODS: Patients older than 60 year-old, with non variceal upper gastrointestinal bleeding demonstrated by endoscopy, who were attended in a third level general hospital from June 2009 to June 2013, were included. Data was analyzed with the ROC (Receiver Operating Characteristic) curve. The area under curve was obtained to assess the Rockall score. RESULTS: One hundred ninety patients were included, 64.2% were males, with an average age of 74 years old. Overall mortality was 16.8% and respiratory failure with second bleeding episode was the most common cause of death (34.3% and 31.3% respectively). 5.52% of patients presented a second bleeding episode. A transfusion of more than 2 blood-packs was needed in the 24.7% of the patients. The area under ROC curve using the Rockall score was 0,76 (IC: 0.68-0.84) for mortality risk, 0.71 (IC: 0.55-0.88) for the risk of rebleeding and 0.66 (IC: 0.58-0.74) for needing a more than 2 blood-packs transfusion. CONCLUSIONS: Rockall score is a good predictor for mortality and rebleeding during the 30 day-period after a non-variceal bleeding episode in elderly patients. The best sensibility and specificity was obtained with the scores of 5 and 6, respectively.

Validación del score de Rockall en pacientes adultos mayores con hemorragia digestiva alta no variceal en un hospital general de tercer nivel / Validation of the Rockall score in elderly patients with non variceal upper gastrointestinal bleeding in a third level general hospital

Objetivo: Validar el score de Rockall en adultos mayores con hemorragia digestiva alta no variceal, como un discriminante de mayor riesgo para mortalidad y recidiva de hemorragia a 30 días de seguimiento. Material y métodos: Se incluyeron los pacientes mayores de 60 años que cursaron con hemorragia digestiva alta no variceal demostrada por endoscopía, desde junio 2009 hasta junio 2013, en un hospital general de tercer nivel. Los datos se analizaron con la curva ROC y se calculó el área bajo la curva para evaluar la utilidad del score de Rockall. Resultados: Entre los 190 pacientes registrados, el 64,2% fueron varones y la edad promedio de 74 ± 9,4 años, teniéndose 29% de pacientes con 80 o más años (55 pacientes). Se halló una mortalidad de 16,8% (32 pacientes), siendo la insuficiencia respiratoria y el resangrado las causas más frecuentes (34,3% y 31,3%). El 6,84% (13 pacientes) tuvieron recidiva de hemorragia y un 24,7% (47 pacientes) necesitó transfusión de más de 2 paquetes globulares. El área bajo la curva ROC para el riesgo de mortalidad fue de 0,76 (IC: 0,68-0,84), para recidiva de hemorragia de 0,71 (IC: 0,55-0,88) y para transfusión de más de 2 paquetes globulares de 0,66 (IC: 0,58-0,74). Conclusión: El score de Rockall es un buen predictor de mortalidad y de recidiva de hemorragia durante los 30 días posteriores a un episodio de hemorragia digestiva altano variceal en adultos mayores, siendo los score 5 y 6, respectivamente, los de mejor sensibilidad y especificidad.
