Behavior and Use of Quaternary Ammonium-Based Disinfectants in Biosafety Protocols Against Fusarium oxysporum f. sp. cubense Race 1 and Tropical Race 4.

The banana is one of Colombia's main export products. However, production is seriously affected by Fusarium wilt of banana, which is the most destructive disease caused by the fungus Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4). Currently, management strategies focus on containment and biosecurity protocols to prevent its spread to territories that are free of this disease. This study aimed to evaluate nine quaternary ammonium-based disinfectants (i.e., quaternary ammonium compounds [QACs]) in vitro in Colombia on reproductive (microconidia and macroconidia) and resistance structures (chlamydospores) of Foc race 1 (R1) and tropical race 4 (TR4), with and without soil, to determine the influence of organic matter and soil texture on the action of QACs. A method for inhibiting the action of QACs was standardized and evaluated at 1,200 ppm with a contact time of ≤30 s while evaluating the soil-inoculum and soil-disinfectant interactions. In the soil-inoculum interaction, the efficacy of QACs was 100% in the reproductive and resistance structures of Foc R1 and TR4 without soil. However, in the soil-disinfectant interaction, only QAC4 controlled the pathogen at 100%. The presence of organic matter influenced the biocidal action of the QACs, and fine textures had a greater reducing effect on the concentration. The soil decreased the efficacy of the QACs and, therefore, must be removed from contaminated boots before treatments are applied.

Hydrogel capsules as new delivery system for Trichoderma koningiopsis Th003 to control Rhizoctonia solani in rice (Oryza sativa).

The incorporation of biological control agents (BCAs) such as Trichoderma spp. in agricultural systems favors the transition towards sustainable practices of plant nutrition and diseases control. Novel bioproducts for crop management are called to guarantee sustainable antagonism activity of BCAs and increase the acceptance of the farmers. The encapsulation in polymeric matrices play a prominent role for providing an effective carrier/protector and long-lasting bioproduct. This research aimed to study the influence of biopolymer in hydrogel capsules on survival and shelf-life of T. koningiopsis. Thus, two hydrogel capsules prototypes based on alginate (P1) and amidated pectin (P2), containing conidia of T. koningiopsis Th003 were formulated. Capsules were prepared by the ionic gelation method and calcium gluconate as crosslinker. Conidia releasing under different pH values of the medium, survival of conidia in drying capsules, storage stability, and biocontrol activity against rice sheath blight (Rhizoctonia solani) were studied. P2 prototype provided up to 98% survival to Th003 in fluid bed drying, faster conidia releasing at pH 5.8, storage stability greater than 6 months at 18 °C, and up to 67% of disease reduction. However, both biopolymers facilitate the antagonistic activity against R. solani, and therefore can be incorporated in novel hydrogel capsules-based biopreparations. This work incites to develop novel biopesticides-based formulations with potential to improve the delivery process in the target site and the protection of the active ingredient from the environmental factors.

Multicenter evaluation of a high-throughput microarray platform for extensive red blood cell phenotyping and antibody screening.

BACKGROUND: Blood typing and antibody screening are key elements of transfusion safety. However, available single platform, flexible, and affordable technologies are limited, especially for extended phenotyping. Microarray-based technology allows for this extended phenotyping with the flexibility of piecemeal analysis. STUDY DESIGN AND METHODS: This study was conducted in three blood donor laboratories to determine the performance of a high-throughput microarray-based system for ABO, RH1-RH5, and KEL1 typing, ABS and extended phenotyping (RH8, KEL2&3, FY1&2, JK1, MNS3). Specimens were tested simultaneously on local platforms and on the microarray-based system. When discrepancies were identified, resolver testing were performed. RESULTS: In total, 4862 blood samples were tested for standard phenotype, 4257 for antibody screening and 2194 for extended phenotype. Results were available for 92.12% of the samples. The overall percent agreements were: 100% for ABO, 99.8% for RH1, 99.24% for RH2-5 and 99.86% for KEL1, 93.16% for antibody screening, and 99.68% for extended phenotype. CONCLUSIONS: This microarray-based system provides highly comparable results to current CE marked assays. The ability to continuously test 3000 microarrays in 1 day, providing simultaneously both extended RBC phenotyping and antibody detection drives laboratory efficiencies. The results of our study validate the performance of this new technology; however, the percentage of samples without results must be reduced and further analysis is required to interpret the ABS screening performances. This could constitute a real breakthrough in transfusion, making it possible in the long term, on a single platform, to carry out all the analyses necessary for the qualification of donations.

Fact-Checking Journalism: A Palliative Against the COVID-19 Infodemic in Ibero-America.

This study explores how fact-checkers understand information disorder in Ibero-America, in particular the COVID-19 disinformation. We conducted a quantitative content analysis of the LatamChequea Coronavirus alliance database and in-depth interviews with journalists from the network. Evidence found that one of the most prevalent disinformation topics was the government's restrictive measures, threatening to jeopardize the effectiveness of public health campaigns. This, added to disinformation that eroded the trust in the institutions and the press, and the opacity of governments constituted a political crisis in Ibero-America. Under this scenario, fact-checkers created relevant journalistic collaborations and strategies to fight disinformation in the region.

Risk factors for reamputation in patients with diabetic foot: A case-control study.

BACKGROUND: Reamputation as a complication of diabetic foot ulcers presents a high economic burden and represents a therapeutic failure. It is paramount to identify as early as possible patients in whom a minor amputation may not be the best option. The purpose of this investigation was to do a case-controlled study to determine risk factors associated with re-amputation in patients with DFU (diabetic foot ulcers) at two University Hospitals. METHODS: Multicentric, observational, retrospective, case-control study from clinical records of 2 university hospitals. Our study included 420 patients, with 171 cases (re-amputations), and 249 controls. We performed a multivariate logistic regression analysis and time-to-event survival analysis to identify re-amputation risk factors. RESULTS: Statistically significant risk factors were artery history of tobacco use (p = 0.001); male sex (p = 0.048); arterial occlusion in Doppler ultrasound (p = 0.001); percentage of stenosis in arterial ultrasound >50 % (p = 0.053); requirement of vascular intervention (p = 0.01); and microvascular involvement in photoplethysmography (p = 0.033). The most parsimonious regression model suggests that history of tobacco use, male sex, arterial occlusion in ultrasound, and percentage of stenosis in arterial ultrasound >50 % remained statistically significant. The survival analysis identified earlier amputations in patients with larger occlusion in arterial ultrasound, high leukocyte count, and elevated ESR. CONCLUSION: Direct and surrogate outcomes in patients with diabetic foot ulcers identify vascular involvement as an important risk factor for reamputation. LEVEL OF EVIDENCE: III.

Nutritional benefits in pediatric patients with percutaneous endoscopic gastrostomy placement.

Gastrostomy is an enteral nutrition option. Indications for its placement are diverse, among them, the alteration in the mechanics of swallowing, frequently present in patients with neurological diseases. Nutritional recovery is the objective in these patients evaluating the nutritional status after the placement of a PEG in the pediatric population. This is a retrospective cohort conducted to evaluate nutritional recovery in pediatric patients with PEG placement. It was performed using anthropometric and biochemical parameters before and after placement. Forty-seven subjects were included, from which weight, height, and upper arm circumference were obtained, to evaluate nutritional recovery using BMI or W/L according to age. Significant nutritional improvement was demonstrated in a population of 39 patients, who had a mean follow-up of 7 months. In our population, PEG is an enteral nutrition strategy that has a significant positive impact on nutritional status in a mean of 7 months after its placement. Therefore, considering the evolution time of these patients will guide the clinician in making decisions regarding surveillance and monitoring parameters of the nutritional status.

Clinical and Epidemiological Characteristics of Paediatric Patients Diagnosed with COVID-19 in a Tertiary Hospital in Mexico City.

COVID-19 affects the paediatric population less frequently than adults. A retrospective study was performed in a tertiary paediatric hospital in Mexico City in children <18 years of age who were hospitalized with a positive reverse transcription-polymerase chain reaction for SARS-CoV-2. Included in the study were 86 patients with a median age of 10 years old (IQR 2.6-14.3 years), who were classified in three groups: previously healthy, with chronic disease and immunosuppressed patients. The principal signs and symptoms were fever (81%), cough (51%) and headache (35%). A total of 20 patients (23%) required management in the paediatric intensive care unit (PICU) and 17% needed mechanical ventilation for an average of 12.7 days (IQR 2-29 days). There was no statistically significant difference between the three clinical classification groups in those patients admitted to the PICU, most of which were previously healthy patients. The mortality rate was 5% (four patients). Given that the paediatric population is susceptible to infection, potential transmitters and to clinical presentations with variable degrees of severity, it is important to continue reinforcing social distancing measures.

Mexican consensus on Hodgkin's lymphoma.

El linfoma de Hodgkin (LH) se debe a la transformación clonal de células originadas en los linfocitos B, lo que genera las células binucleadas patognomónicas de Reed-Sternberg. El LH es una enfermedad de células B con una distribución bimodal, con mayor incidencia en la adolescencia y la tercera década de la vida y un segundo pico en personas mayores de 55 años. Las células del LH clásico habitualmente sufren una reprogramación de la expresión génica, ya que pierden la expresión de la mayoría de los genes típicos de las células B y han adquirido la expresión de múltiples genes que son típicos de otros tipos de células del sistema inmunitario. El algoritmo de tratamiento dependerá si se trata de LH clásico o de predominio linfocítico, si es un estadio temprano con marcadores de pronóstico desfavorables o no, el esquema inicial de manejo y si existe enfermedad voluminosa, entre las variables más relevantes.Hodgkin's lymphoma (HL) is due to the clonal transformation of cells originating from B lymphocytes, generating the pathognomonic binucleate Reed-Sternberg cells. HL is a B cell disease with a bimodal distribution, with higher incidence in adolescence and the third decade of life, showing a second peak in people over 55 years of age. Classic Hodgkin lymphoma cells routinely undergo gene expression reprogramming, as they lose the expression of most of the typical B-cell genes and acquire the expression of multiple genes that are typical of other types of cells in the immune system. The treatment algorithm will depend on whether it is classic or predominantly lymphocytic HL, if it is early stage with unfavorable prognostic markers or not, the initial management regimen, and whether there is bulky disease, among the most relevant variables.

Patients aged ninety years and older are exposed to increased risk of one-year mortality after hip fractures.

BACKGROUND: The increase in the population over 90 years old suggests an expected surge in the number of extreme elderly patients sustaining hip fractures. OBJECTIVE: The aim of this study is to identify factors associated with 1-year mortality and determine the conditions that are associated with an unfavorable survival outcome in nonagenarians. DESIGN: Cross-sectional study SUBJECTS: Nonagenarian patients presenting with hip fractures between 2013 and 2018. METHODS: Bivariate and multivariate analyses were performed to identify variables associated with mortality, and a survival analysis was conducted to determine whether the Charlson Comorbidity Index (CCI) is associated with mortality. RESULTS: A total of 127 patients, with a mean age of 92.84 years was assessed, identifying 1-year mortality rate in 53.5% of patients. According to the bivariate analysis, requirement of postoperative vasopressor support, transfusion, decompensated heart failure and general anesthesia were associated with a higher probability of 1-year mortality after surgery. Body mass index, health status, dementia or CCI ≥ 3 were not associated with mortality. Similarly, the Kaplan-Meier survival analysis showed no difference in mortality rate of patients with CCI ≥ 3 (p = 0.282). CONCLUSION: Patients older than 90 years with hip fractures have higher mortality rates per year than younger patients. Some associations were found, but more studies are needed to reach final conclusions, which could help identify higher-risk patients and be able to implement additional measures.

Derivation and external validation of the SIMPLICITY score as a simple immune-based risk score to predict infection in kidney transplant recipients.

Existing approaches for infection risk stratification in kidney transplant recipients are suboptimal. Here, we aimed to develop and validate a weighted score integrating non-pathogen-specific immune parameters and clinical variables to predict the occurrence of post-transplant infectious complications. To this end, we retrospectively analyzed a single-center derivation cohort of 410 patients undergoing kidney transplantation in 2008-2013 in Madrid. Peripheral blood lymphocyte subpopulations, serum immunoglobulin and complement levels were measured at one-month post-transplant. The primary and secondary outcomes were overall and bacterial infection through month six. A point score was derived from a logistic regression model and prospectively applied on a validation cohort of 522 patients undergoing kidney transplantation at 16 centers throughout Spain in 2014-2015. The SIMPLICITY score consisted of the following variables measured at month one after transplantation: C3 level, CD4+ T-cell count, CD8+ T-cell count, IgG level, glomerular filtration rate, recipient age, and infection within the first month. The discrimination capacity in the derivation and validation cohorts was good for overall (areas under the receiver operating curve of 0.774 and 0.730) and bacterial infection (0.767 and 0.734, respectively). The cumulative incidence of overall infection significantly increased across risk categories in the derivation (low-risk 13.7%; intermediate-risk, 35.9%; high-risk 77.6%) and validation datasets (10.2%, 28.9% and 50.4%, respectively). Thus, the SIMPLICITY score, based on easily available immune parameters, allows for stratification of kidney transplant recipients at month one according to their expected risk of subsequent infection.

Mexican Concensus of Multiple Myeloma.

To identify this increasingly common pathology, known as multiple myeloma (MM), it is necessary to refer to the specific factors that characterize it; to this end, the classic criteria known as CRAB (hyperkalemia, renal failure, anemia, and lytic lesions) are available, in which renal failure is one of the most frequent complications. Recently, three indisputable biomarkers have been described for the diagnostic support for MM, which are: more than 10% of clonal plasma cells in bone marrow or, a biopsy that corroborates the presence of a plasmacytoma, light chain ratio ≥ 100 mg/dL and more than one focal lesion on magnetic resonance imaging. A differential diagnosis for plasma cell leukemia, solitary bone plasmacytoma, and extramedullary plasmacytoma should always be considered. Being this an incurable disease, a lot of research has been done regarding its therapeutic management, whose main objective is the disappearance of plasma cells and the patient clinical improvement. Melphalan was the first drug that showed a benefit in 1958 and afterward, with the addition of a steroid as a second drug, it was possible to improve response rates. Subsequently, different molecules were studied, forming multiple combinations, and achieving better rates of overall survival and progression-free survival. Years later, with the arrival of proteasome inhibitors such as bortezomib, and immunomodulators such as thalidomide and lenalidomide, an important turnaround in the disease has been seen, as deeper responses, more prolonged remissions, and improvement in the quality of life of patients have been achieved. This consensus has the purpose of integrating a group of Mexican specialists and promoting the updating of this pathology.

Para identificar una patología cada vez más común, conocida como mieloma múltiple, es necesario hacer alusión de los factores específicos que la caracterizan. Para ello existen los clásicos criterios conocidos como CRAB (hipercalcemia, insuficiencia renal, anemia y lesiones líticas), siendo la insuficiencia renal una de sus complicaciones más frecuentes. Recientemente se han descrito tres biomarcadores indiscutibles para el apoyo diagnóstico del mieloma múltiple, que son: más del 10% de células plasmáticas clonales en medula ósea o biopsia que corrobora la presencia de un plasmocitoma, relación de cadenas ligeras ≥ 100 mg/dl y más de una lesión focal en resonancia magnética. Se debe tomar siempre en cuenta el diagnóstico diferencial con leucemia de células plasmáticas, plasmocitoma óseo solitario y plasmocitoma extramedular. Al ser una enfermedad incurable, se ha investigado mucho en cuanto al manejo terapéutico, el cual tiene como objetivo principal la desaparición de las células plasmáticas y la mejoría clínica del paciente. El primer fármaco que demostró algún beneficio fue el melfalán en el año 1958 y posteriormente al adicionar un esteroide como segundo fármaco se logró mejorar las tasas de respuesta. Después se fueron estudiando diferentes moléculas, con las que se han realizado múltiples combinaciones, alcanzando mejores tasas de supervivencia global y supervivencia libre de progresión. Años más tarde, con la llegada de los inhibidores de proteosoma como el bortezomib, así como de los agentes inmunomoduladores como la talidomida y la lenalidomida, se presenta un giro importante en la enfermedad, ya que se logran respuestas más profundas, periodo de remisiones más prolongadas y mejoría en la calidad de vida de los pacientes. Este consenso tiene la finalidad de integrar a un grupo de especialistas mexicanos y promover la actualización de esta patología.

Gemcitabine-induced hemolytic-uremic syndrome treated with eculizumab or plasmapheresis: two case reports
.

BACKGROUND: Drug-induced hemolytic-uremic syndrome (HUS) has shown good response to eculizumab (ECU). We present 2 cases of patients with gemcitabine-induced HUS (GEM-HUS), one of whom was treated with ECU and the other with conventional treatment. Patient 1: A 74-year-old male with resected adenocarcinoma of the pancreas started adjuvant treatment with GEM, but after 5 months GEM was discontinued due to acute kidney injury and severe hypertension. Laboratory analyses identified microangiopathic hemolytic anemia (MHA) and thrombocytopenia. Plasmapheresis (Pph) was initiated but was stopped due to a severe adverse reaction. Treatment with ECU was initiated at the time of clinical progression requiring hemodialysis. After 7 doses of ECU, hemolysis and kidney function improved and the patient was able to stop hemodialysis. 1 month after the last dose of ECU serum creatinine (sCr) was 1.8 mg/dL. Patient 2: A 68-year-old male with resected urothelial carcinoma stopped GEM after 2 months due to hematologic toxicity. 1 month later the patient visited the emergency room due to minimal effort dyspnea, hypertension, and peripheral edema. Laboratory analyses showed decreased kidney function, MHA, and thrombocytopenia. Symptomatic treatment was started. After an initial recovery, kidney dysfunction, hemolysis, and thrombocytopenia progressed. Corticoid boluses were ineffective and hemodialysis was initiated. Eleven Pph treatments were necessary to recover hematologic data. The patient remained on hemodialysis for 2 months and evolved to stage IV chronic kidney disease. 8 months after hospital release, sCr was 3.5 mg/dL. CONCLUSION: ECU successfully improved kidney function in a patient with GEM-HUS, while conventional treatment did not.

Adherence to a predefined vaccination program in patients with inflammatory bowel disease.

INTRODUCTION: The application of vaccination programs in patients with inflammatory bowel disease (IBD) is heterogeneous and generally deficient. As a result, adherence in these patients to a predefined vaccination program has not been clearly established. The aim of this study was to estimate adherence to a predefined vaccination program among patients with IBD and to identify the factors that may predict poor adherence. METHODS: All patients diagnosed with IBD and followed-up between January and March 2012 were referred to the Department of Preventive Medicine for evaluation of their immune status (with serological testing for hepatitis A, B and C viruses, varicella-zoster virus, mumps, rubella and measles), followed by vaccination based on the test results obtained and on the patient's vaccination history. The percentage of adherence to the vaccination program was determined, along with the factors associated with low adherence. RESULTS: A total of 153 patients with IBD (ulcerative colitis in 50.3% and Crohn's disease in 49.7%) were included (45.1% men and 54.9% women; mean age 43.30±14.19 years, range 17-83). The vaccination program adherence rate was 84.3%. The factors associated with poor adherence were drugs related to IBD (patients not receiving immunosuppressants and/or biological agents showed lower adherence than those receiving these treatments; p=0.021), adherence to medical treatment (poor adherence to treatment was also associated with poor adherence to vaccination; p=0.016), and marital status (single, divorced or separated patients showed lower adherence than married individuals; p=0.015). CONCLUSION: Adherence to vaccination is acceptable among patients with IBD. However, specific actions, such as optimization of patient information on the disease and emphasis on the need for adequate vaccination, are to improve adherence.

Germline mutations in NKX2-5, GATA4, and CRELD1 are rare in a Mexican sample of Down syndrome patients with endocardial cushion and septal heart defects.

Congenital heart defects (CHD) are found in ~50 % of Down syndrome (DS) patients. Genetic variants have been implicated, including CRELD1 mutations, but no previous study has examined the candidate genes, NKX2-5 and GATA4, in DS patients with secundum atrial defects (ASDII) and ventricular septal defects (VSD). Furthermore, CRELD1 mutations have not yet been studied in Mexican DS patients with atrioventricular septal defects (AVSD). Mexican DS patients (n = 148) with standard trisomy 21 were classified as follows: group I, normal heart; group II, VSD, ASDII, or both; and group III, AVSD. Mexican healthy controls (n = 113) were also included. Sequence analysis was performed on NKX2-5 and GATA4 in all three groups, and on CRELD1 in only group III. Statistical differences in the percentages of functional variants were analyzed by Fisher's exact test. Three non-synonymous variants in NKX2-5 were identified in the heterozygous state: a novel p.Pro5Ser was found in one DS patient without CHD; the p.Glu21Gln was found in one ASDII patient; and the p.Arg25Cys (R25C) was found in three patients (one from each DS study group). The p.Glu21Gln and R25C were also documented in 0.88 % of the controls. No significant difference was observed between the DS groups and healthy controls. Germline mutations in the NKX2-5, GATA4, and CRELD1 genes do not appear to be associated with CHD in Mexican DS patients. Our findings also support the notion that the R25C variant of NKX2-5 is a polymorphism, as it was not significantly different between our DS patients and controls.

Identification of biomedical journals in Spain and Latin America.

OBJECTIVES: Journals in languages other than English that publish original clinical research are often not well covered in the main biomedical databases and therefore often not included in systematic reviews. This study aimed to identify Spanish language biomedical journals from Spain and Latin America and to describe their main features. METHODS: Journals were identified in electronic databases, publishers' catalogues and local registries. Eligibility was determined by assessing data from these sources or the journals' websites, when available. FINDINGS: A total of 2457 journals were initially identified; 1498 met inclusion criteria. Spain (27.3%), Mexico (16.0%), Argentina (15.1%) and Chile (11.9%) had the highest number of journals. Most (85.8%) are currently active; 87.8% have an ISSN. The median and mean length of publication were 22 and 29 years, respectively. A total of 66.0% were indexed in at least one database; 3.0% had an impact factor in 2012. A total of 845 journals had websites (56.4%), of which 700 (82.8%) were searchable and 681 (80.6%) free of charge. CONCLUSIONS: Most of the identified journals have no impact factor or are not indexed in any of the major databases. The list of identified biomedical journals can be a useful resource when conducting hand searching activities and identifying clinical trials that otherwise would not be retrieved.

[Efficacy and safety of ciprofloxacin treatment in urinary tract infections (UTIs) in adults: a systematic review with meta-analysis]. / Eficacia y seguridad de la ciprofloxacina en el tratamiento de las infecciones de las vías urinarias (IVU) en adultos: revisión sistemática con metaanálisis.

OBJECTIVES AND DESIGN: A systematic review with meta-analysis of randomized controlled trials (RGT) on the efficacy and safety of ciprofloxacin in the treatment of acute or complicated urinary tract infections in adults. Primary outcomes were bacteriological eradication, clinical cure, bacterial resistance, and adverse event rates. RESULTS: Initially, 111 RGTs were identified. We excluded 81 studies due to low quality methodology. An analysis of the remaining RGTs identified therapeutic equivalence of ciprofloxacin against other antimicrobials in terms of bacterial eradication and clinical cure at the end of treatment and in subsequent stages. The percentage of bacterial resistance was similar in both groups, while the percentage of related adverse events was significantly lower in the groups treated with ciprofloxacin. CONCLUSIONS: We conclude that ciprofloxacin is a safe and effective therapeutic alternative for the treatment of acute or complicated urinary tract infections in adults.

[Efficacy of racecadotril vs. smectite, probiotics or zinc as an integral part of treatment of acute diarrhea in children under five years: A meta-analysis of multiple treatments]. / Eficacia del racecadotrilo versus smectita, probióticos o zinc como parte integral del tratamiento de la diarrea aguda en menores de cinco años: meta-análisis de tratamientos múltiples.

RATIONALE: Despite major advances in treatment, acute diarrhea continues to be a public health problem in children under five years. There is no systematic approach to treatment and most evidence is assembled comparing active treatment vs. placebo. OBJECTIVE: Systematic review of evidence on efficacy of adjuvants for treatment of acute diarrhea through a network meta-analysis. METHODS: A systematic search of multiple databases searching clinical trials related to the use of racecadotril, smectite, Lactobacillus GG, Lactobacillus reuteri, Saccharomyces boulardii and zinc as adjuvants in acute diarrhea was done. The primary endpoint was duration of diarrhea. Information is displayed through network meta-analysis.The superiority of each coadjutant was analyzed by Sucra approach. RESULTS: Network meta-analysis showed race cadotril was better when compared with placebo and other adjuvants. Sucra analysis showed racecadotril as the first option followed by smectite and Lactobacillus reuteri. INTERPRETATION: Considering a strategic decision making approach, network meta-analysis allows us to establish the therapeutic superiority of racecadotril as an adjunct for the comprehensive management of acute diarrhea in children aged less than five years.

Safety of soya-based infant formulas in children.

Soya-based infant formulas (SIF) containing soya flour were introduced almost 100 years ago. Modern soya formulas are used in allergy/intolerance to cows' milk-based formulas (CMF), post-infectious diarrhoea, lactose intolerance and galactosaemia, as a vegan human milk (HM) substitute, etc. The safety of SIF is still debated. In the present study, we reviewed the safety of SIF in relation to anthropometric growth, bone health (bone mineral content), immunity, cognition, and reproductive and endocrine functions. The present review includes cross-sectional, case-control, cohort studies or clinical trials that were carried out in children fed SIF compared with those fed other types of infant formulas and that measured safety. The databases that were searched included PubMed (1909 to July 2013), Embase (1988 to May 2013), LILACS (1990 to May 2011), ARTEMISA (13th edition, December 2012), Cochrane controlled trials register, Bandolier and DARE using the Cochrane methodology. Wherever possible, a meta-analysis was carried out. We found that the anthropometric patterns of children fed SIF were similar to those of children fed CMF or HM. Despite the high levels of phytates and aluminium in SIF, Hb, serum protein, Zn and Ca concentrations and bone mineral content were found to be similar to those of children fed CMF or HM. We also found the levels of genistein and daidzein to be higher in children fed SIF; however, we did not find strong evidence of a negative effect on reproductive and endocrine functions. Immune measurements and neurocognitive parameters were similar in all the feeding groups. In conclusion, modern SIF are evidence-based safety options to feed children requiring them. The patterns of growth, bone health and metabolic, reproductive, endocrine, immune and neurological functions are similar to those observed in children fed CMF or HM.
